-2^2-3(-3+6)/(-1)(2) solve?






If so then first think of PEMDAS, which stand for :

P - Parenthesis (first)
E- Exponent (second)
M - Multiplication (third /fourth : interchangeable with Division)
D - Division (Third/fourth: interchangeable with multiplication)
A - Addition (Fifth/ sixth: interchangeable with subtraction)
S- Subtraction (Fifth/sixth: Interchangeable with addition)

Keep in mind that “MD” and “AS” in PEMDAS are usually done from left to right.

Once you know that look at your equation , we have two set of parenthesis one on top and the other in the bottom, so we solve what are in the parenthesis first (my apologize for not actually using the terms here, I personally am not sure how to type it properly)

on top we have (-3+6) so basically you are adding negative three to a positive 6 , keep in mind one negative cancel out a positive therefor this leave us with a positive (3)

you can also think of this as subtracting the two numbers , ignoring the sign and than take the sign of the bigger number when signs are opposite. So, 6 minus 3 is 3 and 6 is bigger than 3 so we get a positive 3.

Now taking a look at the bottom one , we really don’t have parenthesis but just one set of multiplication, so we can simply just take care of this, since we have nothing to interfere with the bottom one yet.

Keep in mind when it comes to multiplication you must know the rule of the signs:

  1. Opposite signs (positive times a negative, or negative times a positive) will always result in a negative

  2. Same signs (positive times a positive , or negative times a negative) will always result in a positive’

with that we can be clear that a negative sign we will end up with due to the two numbers being opposite signs, 1 times 2 = 2 include the negative so we have (-2)

now we have :
