Solve like this pls ————>

7 - 3 = 4

1 - (-12) = 13

9 + 11 = 20

7 - (-4) = 28

6 × (-3) = -18

(-8) × 9 = -72

5 + (-8) = -40

(-13) -2 = -26

(-13) + (-5) = 65

(-15) × -1 = 16

(-11) -12 = 132

(-9) × 3 = -27

14 + 8 = 22

60 ÷ (-4) = -15

(-4) + (-14) = -18

20 ÷ 5 = 4

(-12) + 8 = -96

6 + 11 = 17

(-14) × 7 = -98

(-12) - 15 = 180

12 × 13 = 156

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
