Answer: -2
Step-by-step explanation: When you're adding and subtracting positives and negatives, it helps to use a number line to visualize what's going on. On a number line, 0 is in the middle and all number to the right of 0 are positive and all numbers to the left of 0 are negative.
When we are simplifying a problem like -6 + 4, we start at 0 and -6 moves us 6 units to the left along our number line. From there, positive 4 then moves us 4 units back to the right and we end up at -2.
This means that -6 + 4 = -2.
