Do you multiply exponents or multiply first?
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.
How do you multiply exponents step by step?
When you’re multiplying exponents, remind students to:
- Add the exponents if the bases are the same.
- Multiply the bases if the exponents are the same.
- If nothing’s the same, just solve it.
What is the division rule for exponents?
Correct answer: To divide them, you take the exponent value in the numerator (the top exponent) and subtract the exponent value of the denominator (the bottom exponent). Here that means we take 7 – 3 so our answer is x4.
Does multiplication always come first?
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Next, add and subtract from left to right. (Note that addition is not necessarily performed before subtraction.)
Do you multiply first if no brackets?
Because there are no parentheses and exponents, start with the multiplication and then division, working from left to right.
Is there an easy way to solve the square of binomial?
Squaring a binomial can be done using two different methods. Step 1: Square the first term of the binomial. Step 2: Multiply the first term and last term of the binomial together and then double that quantity (in other words multiply by 2). Step 3: Square the last term of the binomial.

Which method do you use to multiply out brackets?
When multiplying out a pair of brackets, multiply each term in the first bracket by each term in the second bracket. So that this doesn’t become too confusing, we use FOIL to help us.
