Question

8−6÷2+3×5= 7×3−15÷5= 8+2(1+12÷2)^2=

Answer 1

Recall that the order of the operations PEMDAS

1. Parenthesis

2. Exponents.

3. Multiplication.

4. Division.

5. Addition.

6. Subtraction.

1. Given expression is

`8-6/2+3*5`

Multiply 3 and 5, we get

`8-6/2+3*5=8-6/2+15`

Divide 6 by 2, we get

`=8-3+15`

Subtract 3 from 8, we get

`=5+15`

Add 5 and 15, we get

`=20`

The answer is

`8-6/2+3*5=20`

2.Given expression is

`7*3-15/5`

Multiply 7 and 3, we get

`7*3-15/5=21-15/5`

Divide 15 by 5, we get

`=21-3`

Subtract 3 from 21, we get

`=18`

The answer is

`7*3-15/5=18`

3. Given expression is

`8+2(1+12/2)^2`

First, we need to solve inside the parenthesis, divide 12 by 2, we get

`8+2(1+12/2)^2=8+2(1+6)^2`

Add 1 and 6, we get

`=8+2(7)^2`

Solve exponent.

`=8+2(49)`

Multiply 2 and 49, we get

`=8+98`

Add 8 and 98, we get

`=106`

The answer is

`8+2(1+12/2)^2=106`
