Question 461825: simplify
what are the steps for this?
Answer by math-vortex(648)   (Show Source):
You can put this solution on YOUR website! When we have nested parentheses like these, we want to start with the innermost parentheses and work our way out. We will also need to be careful about all those negative signs.
.
-3[-69-(52-70)]=
.
First, we carry out the subtraction inside the inner parentheses. Since 52 - 70 = -18, we simplify to
-3[-69-(-18)]=
.
The negative sign in front of (-18) means: -1*(-18)= 18; we simplify to,
-3[-69+18]=
.
Now we add: -69 + 18 = -51, so we simplify to,
-3[-51]=
.
Finally, we multiply: -3 * (-51) = 153.
.
Hope this helps!
