Why is 6 2 1 2 )= 9 not 1?

The correct answer to the expression 6 ÷ 2 ( 1 + 2 ) 6 ÷ 2 ( 1 + 2 ) is 9, according to modern mathematical conventions like the order of operations (PEMDAS/BODMAS), primarily because multiplication and division are performed with equal priority from left to right. The answer is not 1 because that result stems from an outdated or less common convention where implied multiplication is given higher precedence than division.

Is 6 2 1 2 9 or 1?

6÷2(1+2) 6÷2(3) same as 6/2×3 left-to-right 3×3 9 The ONLY mathematically CORRECT answer is 9 by CORRECTLY applying the 4-step process of either the BO(DM)(AS) or PE(MD)(AS) or GE(MD)(AS) or other "acronyms" for the centuries-old "universal" ORDER OF OPERATIONS RULE.

What's the trick to remembering PEMDAS?

The trick to remembering PEMDAS is using the mnemonic "Please Excuse My Dear Aunt Sally" and understanding that Multiplication/Division and Addition/Subtraction have equal priority, solved from left to right. So, it's P (Parentheses/Grouping), E (Exponents), MD (Multiplication & Division left-to-right), AS (Addition & Subtraction left-to-right).
 

Is the BODMAS rule correct?

Yes, BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) is a correct and widely used acronym to remember the order of operations in mathematics, ensuring consistent answers, though it's often used interchangeably with PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) or BIDMAS (Brackets, Indices, Division, Multiplication, Addition, Subtraction). The key is following the hierarchy: brackets first, then powers/orders, then multiplication and division (left to right), and finally addition and subtraction (left to right).
 

Is BODMAS right or PEMDAS?

Both PEMDAS and BODMAS (or BIDMAS) are correct as they represent the same universal order of operations, just with different terminology (Parentheses vs. Brackets, Exponents vs. Orders/Indices) and a common misconception that multiplication always comes before division or addition before subtraction. The crucial point is that Multiplication/Division and Addition/Subtraction have equal precedence and are done left-to-right, which makes the order within the acronym slightly misleading, so it's better understood as PE(MD)(AS) or BO(DM)(AS).

What are the 5 basic rules of algebra?

The 5 fundamental rules of algebra are the Commutative Laws, Associative Laws, Distributive Law, Identity Laws, and Inverse Laws, which govern how numbers and variables can be rearranged and combined through addition and multiplication, forming the basis for simplifying expressions and solving equations. 

Why is PEMDAS wrong?

The third is that addition always come before subtraction. The last is that everything you would solve the pieces of an equation from left to right, not always following the PEMDAS order. Not only does this problem occur in middle school, but it is apparent in adults as well.

How do you say "I love you" in math?

You can say "I love you" in math through simple number codes like 143 (1 letter, 4 letters, 3 letters), using math-themed symbols like I < 3 u, solving an inequality like 9x - 7I > 3(3x - 7U) to reveal "I heart you," or by graphing equations that form a heart shape, with popular ones being the cardioid or variations like the heart curve. 

What is the 6174 trick in math?

The 6174 number trick, also known as Kaprekar's Routine, involves taking any four-digit number (with at least two different digits), arranging its digits to form the largest and smallest possible numbers, and subtracting the smaller from the larger; this process, when repeated, will always lead to the number 6174, known as Kaprekar's Constant. 

What defines a "correct" answer?

A 'correct answer' is defined as a response that accurately reflects the right solution to a question, contributing to the total score in a testing scenario, as exemplified by the calculation of maximum possible correct answers in a group of questions.

What is 0.333333333333333 as a fraction?

Step 2: Multiply both sides of the equation by 10 to move the decimal point one place to the right. 10x = 3.333333333333333... Thus, 0.333333333333333 can be written as the fraction 1/3.

What are common PEMDAS mistakes?

Common Mistakes When Using PEMDAS

Forgetting Left-to-Right Rule: Multiplication and division, as well as addition and subtraction, must be performed in order from left to right. ❌ Wrong: 30 ÷ 5 × 3 = 30 ÷ 15 = 2.

When did PEMDAS change?

As of the current date, there has been no official change to the PEMDAS order of operations. It remains the widely accepted standard for evaluating mathematical expressions across various disciplines.

What did "o" stand for in BODMAS?

In BODMAS, O stands for Orders. In BIDMAS, I stands for Indices. The acronym reminds us of the order in which calculations are carried out. Brackets are always tackled first. Orders/Indices, such as cube numbers or square roots, are dealt with next.

What is 1 ➗ 0 and why?

As much as we would like to have an answer for "what's 1 divided by 0?" it's sadly impossible to have an answer. The reason, in short, is that whatever we may answer, we will then have to agree that that answer times 0 equals to 1, and that cannot be ​true, because anything times 0 is 0.

What is DMAS in maths?

The Full Form of DMAS is Division, Multiplication, Addition, and Subtraction. The acronym DMAS is widely recognized and utilized in mathematics education to help students understand and remember the order of operations when solving mathematical problems.

What is the answer to 11 11x11 11 only for genius?

-99 (PE)MDAS 11-11x11+11= Multiplication (11x11) = 11-121+11 ̶̶D̶̶i̶̶v̶̶i̶̶s̶̶i̶̶o̶̶n (yes, Pemdas. So the Multiplication and Division can change, And so does addition and subtraction, as its left to right.) Subtraction (11-121) =-110+11 Addition (-110+11) =-99 Therefore the answer is -99.

What can bend but never break?

Glass that bends but doesn't break has been created by researchers at McGill University. The trick is a series of engraved microcracks, which allow the glass to deform on impact and increases its toughness 200 times, according to a study in Nature Communications.

Which three riddles died?

When Riddle learned from his maternal uncle Morfin Gaunt that the former's father was a Muggle, the younger Riddle proceeded to the Riddle House. Once in the house, he murdered his father, paternal grandfather, and grandmother with the Killing Curse.
