How do you simplify #2[-4+3(-7+4)]# using PEMDAS?
Start with the innermost bracket and work out to get
PEDMAS refers to the order in which we solve an equation:
Parentheses (I tend to call them Brackets)
Let's start with the original:
So we have 2 times a big bracket and within that bracket there is 3 times a smaller bracket. Since we do brackets first and the innermost brackets:
We can multiply the 3 by the result of the small bracket (-3):
There is only one term, but there are 2 terms inside the square bracket. Work from the inner bracket.
