Answer:
1) -4
2) -18
3) -25
Step-by-step explanation:
1)
-6 + -8 = -14
-14 + 10 = -4
2)
Any number multiplied by a negative number will result in a negative product.
So what I do is I multiply as if there was no negative sign: 3 × 6 = 18
Then I add the negative sign to the product: -18
3)
One way you could do this is by switching it around: 18 - -7
Which would make it: 18 + 7 = 25
Then add the negative sign: -25
