Subtract. –5.8 – (–8.4) A. –14.2 B. –2.6 C. 2.6 D. 14.2
svp [43]
-5.8 - (-8.4)

When we multiply two negatives they become a positive. In this situation, where there is no other number, you can assume there's basically a 1 in that place. 

-5.8 - 1(-8.4) would be just as correct. (If this helps visually clarify anything.)

So we take that -1 and multiply it by that -8.4. Multiplying 1 against anything leaves it the same, so we just need to change the sign. Two negatives make a positive. 

-5.8 + 8.4

Now we add these together.

This gives us our final answer of 2.6
