Simplifying Math2

Bellwork Switch all the subtractions in the following expressions to adding the opposite: Example: 4 – x – 7 + 2 = 4 + (-x) + (-7) + 2 5. 6. 7. 8.

5–y–3= g+4–6= m + 6 – 2m = h – 6h – 9 – 4 + h =

NEWSFLASH!!!! Subtraction IS THE SAME AS Adding the Opposite!!!!!!

To make things easier to solve…… ….turn all subtractions in to ADDING THE OPPOSITE

Rewrite any SUBTRACTION as ADDING THE OPPOSITE • • • • •

x – 6 = x + (-6)  EASY EXAMPLE ! y – 12 = y + (-12) g – 14 + 13 = g + (-14) + 13 h + 4 – (-3) – 5h = h + 4 + 3 + (-5h) (-5m) – 5 + 4m – 4 – 5 + m – 3m = (5m) + (-5) + 4m + (-4) + (-5) + m + (-3m)

Now simplify them!! Easy!

= g + (-1)

g + (-14) + 13 h + 4 + 3 + (-5h)

= -4h + 7

(5m) + (-5) + 4m + (-4) + (-5) + m + (-3m)

= 7m + (-14)
