What is the 25 * 25 trick?

Trick 2: Squares of similar numbers ending with 5s

Multiplying two numbers ending in 5s is done by multiplying the left side of the numbers with one of them incremented and then adding 25 at the end. For example, 25 x 25 is (2×3)=6 is the prefix and add 25 as the postfix to it. So, the answer is 625.

What is the trick for 999 in math?

The popular 999 math trick for multiplication involves subtracting 1 from your number, then subtracting that result from 999 to get the second part of your answer, effectively turning N×999cap N cross 999𝑁×999 into (N−1)open paren cap N minus 1 close paren(𝑁−1) followed by (999−(N−1))open paren 999 minus open paren cap N minus 1 close paren close paren(999−(𝑁−1)), as shown in this YouTube video and explained by Cut-the-Knot.org and Zero Math, making complex multiplication much faster by using 1000−11000 minus 11000−1 as the basis, notes this Facebook post. 

Which three numbers add up to 30 1 3 5 7 9 11 13 15?

The sum of three odd numbers will always be odd (because odd + odd = even, and even + odd = odd). Since 30 is an even number, adding three odd numbers can never equal 30. Thus, with the given numbers, it is impossible to find three numbers whose sum is exactly 30 if we assume standard addition.

What times 25 will give you 100?

25 × 4 = 100. 25 × 5 = 125. 25 × 6 = 150. 25 × 7 = 175.

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 math says "I love you"?

In math, "I love you" often translates to the number 143, representing the count of letters in each word (1 for "I", 4 for "Love", 3 for "You"). Other symbolic interpretations include using the heart symbol (<3), equations like 1+∞+11 plus infinity plus 11+∞+1 (I + Love + You) or complex graphs, but 143 is the most common numeric code.
 

Is BODMAS or PEMDAS correct?

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).
 

How to get an a * in maths?

To get an A\* in Maths, focus on consistent, deep practice (especially past papers), mastering fundamentals, identifying and targeting weaknesses, understanding why solutions work (not just memorizing), and developing strong exam technique by working under timed conditions and using mark schemes effectively. Prioritize understanding concepts over rote learning, use varied resources, and establish a structured revision plan with regular review of older topics to prevent forgetting. 

How to get 100% marks in maths?

To get 100 in maths, master concepts through intense practice, focus on formulas and definitions, solve previous year papers to understand exam patterns, diligently do homework, and eliminate silly mistakes by careful revision, treating maths like a puzzle to be solved systematically, not just memorized. 

What is a 70% out of 100% grade?

A score of 70% typically earns a letter grade of a C, or sometimes a C-, depending on the specific grading scale used by the school or instructor, with ranges often placing 70-79% as a "C" and 70-72% as a "C-". For a 100%, the grade is usually an A+ or an A, signifying excellent performance.
 

Which table 125 will come in?

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 the math code for "I love you"?

Saying "I love you" with math involves numeric codes like 143 (1 letter 'I', 4 'love', 3 'you'), programming snippets that print the phrase, or complex graphing equations that draw a heart, showing love through numbers, code, or visual patterns. Other creative ways include calculator tricks (typing 71077345 and flipping), using the Golden Ratio (φ), or symbolic equations like 3sin(x)−2sin(2x)+sin(3x)=03 sine x minus 2 sine 2 x plus sine 3 x equals 03sin(𝑥)−2sin(2𝑥)+sin(3𝑥)=0. 

What is the hardest math problem in the world?

There isn't one single "hardest" math problem, but the Riemann Hypothesis is often cited due to its profound implications for prime numbers and its status as a 1millionMillenniumPrizeProblem1 m i l l i o n cap M i l l e n n i u m cap P r i z e cap P r o b l e m1𝑚𝑖𝑙𝑙𝑖𝑜𝑛𝑀𝑖𝑙𝑙𝑒𝑛𝑛𝑖𝑢𝑚𝑃𝑟𝑖𝑧𝑒𝑃𝑟𝑜𝑏𝑙𝑒𝑚. Other contenders for the toughest include the {P vs. NP Problem} (computer science), {Navier-Stokes Existence and Smoothness} (fluid dynamics), and the deceptively simple {Collatz Conjecture} (number theory).
