Question

6 – 4(3 – 5)^2 + 30 ÷ 5? can someone help with the order key

Answer 1

Just remember: Please Excuse My Dear Aunt Sally

Parentheses then Exponents then Multiplication or Division (doesn't matter which first) then Addition or Subtraction (doesn't matter which first.

6 - 4(3-5)^2 +30 divided by 5 (sorry can't find the division key)

So first we do the parentheses:

Answer 2

(3-5) = (-2)

Then we do the exponents

(-2)^2 = 4

Answer 3

We then have the equation => 6 - 4(4) + 30 divided by five

So we can choose whether to divide or multiply first as it doesn't matter, we'll do it all before starting to subtract or add.

this give -4(4) = -16

and 30 divided by 5 = 6

This gives the equation => 6 - 16 + 30 and you can take it from here :)
