once you upload beneficial integers, your sum is beneficial. whilst subtracting unfavorable integers this is like including a unfavorable to an outstanding. as an occasion, a million - (-a million) = a million + a million whilst multiplying, a unfavorable and an outstanding will replace right into a unfavorable. an outstanding and a unfavorable is a unfavorable an outstanding and an outstanding is an outstanding and a unfavorable and a unfavorable is an outstanding. 12x+4x = 16x

I learned the phrase "Please Excuse My Dear Aunt Sally"
the first letters, P E M D A S stand for parenthesis, exponents, multiplication AND division, addition AND substration.
So you strat at the left of the equation and look for any parenthesis. Solve anything in parenthesis going left to right.
Next is exponents. From the left of the equation to the right.
Then Multliplication AND division from left to right.
Then Addition AND substration from left to right.
