What does ∏ mean?

The symbol ∏ (capital Greek letter Pi) means product, representing the multiplication of a sequence of terms, similar to how ∑ (capital Sigma) means summation. It's used in mathematics for large products, often with limits, like ∏i=1naiproduct from i equals 1 to n of a sub i𝑛𝑖=1𝑎𝑖 meaning a1×a2×…×ana sub 1 cross a sub 2 cross … cross a sub n𝑎1×𝑎2×…×𝑎𝑛. It also has specific uses in science, representing osmotic pressure (π) or product of sums (Boolean algebra).

What does ∈ mean in math?

In math, the symbol ∈ means "is an element of," indicating that the item on the left is a member of the set on the right, like x∈Rx is an element of the real numbers𝑥∈ℝ (x is a real number) or 3∈{1,2,3}3 is an element of the set 1 comma 2 comma 3 end-set3∈{1,2,3} (3 is in the set containing 1, 2, and 3). Its negation, ∉, means "is not an element of," as in 4∉{1,2,3}4 is not an element of the set 1 comma 2 comma 3 end-set4∉{1,2,3}. 

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"?

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 rare is a 800 SAT math?

An 800 on the SAT Math section is extremely rare, placing you in the top 1% (99th percentile) of all test-takers, meaning less than 1% of students achieve this, often requiring significant effort for those last few points due to tricky questions and potential silly errors. While the exact percentage varies slightly, it's a truly exceptional score, though more common among high-achieving groups and international students, notes PrepScholar and College Confidential Forums. 

Is 1 or 0 the first number?

It depends on the context: 1 is the first counting number (natural numbers), used for counting objects, while 0 is often considered the first number in sets like integers or for zero-based indexing (like computers) because it represents "nothing" before you start counting positive values. So, if you're counting apples, you start with 1; if you're defining number sets or programming, 0 is often the starting point.
