Order of operations tells you to perform multiplication before addition. Then add. Simplify 20 – 16 ÷ 4. Order of operations tells you to perform division before subtraction.The order of operations can be remembered by the acronym PEMDAS, which stands for: parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right. There are no parentheses or exponents, so start with multiplication and division from left to right.So, when parentheses are involved, the rules for order of operations are: Do operations in parentheses or grouping symbols. Multiply and divide from left to right. Add and subtract from left to right.

What is the correct order of operations in math?
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Does Bodmas apply if no brackets?
Ans: Yes, we use the BODMAS rule to get the correct answer even if there are no brackets. If there are no brackets, start solving from ‘order’ or ‘of’ followed by Division or multiplication (whatever comes first from left to right) then by addition or subtraction (whatever comes first from left to right).
Why do we multiply before we add?
– Because multiplication is more powerful than addition. We always do what is more powerful first. Any other ideas to add to that? – It’s repeated addition so we can break down to an easier way to understand.

What is the rules of multiplication?
The multiplication rule is a way to find the probability of two events happening at the same time (this is also one of the AP Statistics formulas). There are two multiplication rules. The general multiplication rule formula is: P(A ∩ B) = P(A) P(B|A) and the specific multiplication rule is P(A and B) = P(A) * P(B).
What are the rules for addition?
Rules of integers for addition and subtraction : 1) If the two numbers have different sign like positive and negative then subtract the two numbers and give the sign of the bigger number. 2) If the two numbers have same sign i.e. either positive or negative signs then add the two numbers and give the common sign.
