What is the sum of –356.1 + 258.6
xxTIMURxx [149]

Answer:

Step-by-step explanation:

-356.1 + 258.6 = -97.5

Imagine a long timeline with 0 in the middle, on the left we have -356.1 and on the right we have 356.1. Adding numbers makes the timeline move right.

Starting from the left, add (+) 258.6 to the number (moving right along the timeline). As 356 is larger than 258, the scale does not reach 0 yet and therefore the number must be negative.

Using this logic, the answer is 97.5
