Question

А) 14:7*9+6*(13-7)= б) 15+7*(18:3)-(9+8)= в)4*7-(5*6-3)+8*3=

Answer 1

а) 14:7*9+6*(13-7)= 2*9+6*6=18+36=54

б) 15+7*(18:3)-(9+8)=15+7*6-17=15+42-11=46

в)4*7-(5*6-3)+8*3=28-27+24=25

Answer 2

А)

We can solve this expression using the order of operations, also known as PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction):

14:79+6(13-7)

= 29 + 6(6)

= 18 + 36

= 54

Therefore, 14:79+6(13-7) equals 54.

Б)

Again, we can use the order of operations:

15+7*(18:3)-(9+8)

= 15 + 7*(6) - (9+8)

= 15 + 42 - 17

= 40

Therefore, 15+7*(18:3)-(9+8) equals 40.

В)

47-(56-3)+8*3

= 28 - (30-3) + 24

= 28 - 27 + 24

= 25

Therefore, 47-(56-3)+8*3 equals 25.
