Answer:
1. 6
2. -5
3. -3
Step-by-step explanation:
1. Since there are 2 negatives, they cancel out to create a positive. 18/3=6. The answer, is 6
2. Since there is only 1 negative, just do 20/4 and add a negative in front. 20/4= 5, then add the -, then boom, -5.
3. Again, 1 negative. 21/7=3. Add the negative, boom, -3.
