Explain how to evaluate (-9)(-6)(15)(-7+7) as simply as possible.

For this case we must explain how to simplify the following expression:

( -9)(-6)(15)(-7+7)

According to the PEMDAS algebraic resolution order method, operations within parentheses must be performed first.

So, we have:

-7+7

Different signs are subtracted and the major sign is placed.

-7+7=0

Rewriting the original expression we have:

(-9)(-6)(15)(0)=

Every number multiplied by "0" results in "0".

Then, the expression is zero.

(-9)(-6)(15)=0

(-9)(-6)(15)(-7+7)=0

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
