Answer 1

В первом 10 а во втором -15

Answer 2

(+6)+(+4)=6+4=10
(-9)-(-6)=(-9)+6=(-3)

Answer 3

Let's solve these mathematical expressions step by step:

1. (+6) + (+4) = ? When you add two positive numbers, you simply add their values together: (+6) + (+4) = 6 + 4 = 10

2. (-9) - (-6) = ? When you subtract a negative number from another negative number, it's like adding their absolute values together and keeping the negative sign of the larger number. (-9) - (-6) = (-9) + 6 = -3

So, the answers are:

1. (+6) + (+4) = 10
2. (-9) - (-6) = -3
