Question

Show me how to solve problem -82 + (-43)=

Answer 1

-82-43=-125

.................

Answer 2

Given: -82 + (-43)  

First, remove/expand the brackets.   (positive number/sign) times (negative number/sign) is (negatve number/sine).　So, (+1) x (-4) = -4   We get:

-82 + (-43) = -82 - 43　

Consider a holizontal number line where a number goes right if it increases, it goes left if it decreases.   This problem requires the point, -84, to go left 43 more units.   Moving the point, -84, to left 43 more units is the same process as putting 84 and 43 into brackets marked with negative sign.  So, we get:

-82 - 43 = -(82 +43) = -125 

Therefore, the answer is: -82 + (-43) = -125
