Question

Show the work:

1. 3 + 4[13 - 2(6 -3)]

2. 5[2(8 + 5) - 15]

3. 14 divided by[3(8 - 2) - 11]

Answer 1

1. 3+4[13-2(3)]

3+4[13-6]

3+4(7)

3+28

31

2. 5[2 (13) -15]

5[ 26-15]

5 ( 11)

55

3. 14 divided by [3(6) -11]

    -------------------[18-11]

-----------------------[7]

14 divided by 7

2

good luck!

Answer 2

1. Do what is inside the most inside parentheses

3+4[13 - 2 (6-3)] = 3+4[ 13 - 2 (3)]

Multiplication before subtraction in the brackets.

3+4[ 13 - 2 (3)] = 3+4[ 13 - 6 ]

Inside brackets again

3+4 [ 13 - 6] = 3+4 [ 7 ]

Multiply

3 + 4[7] = 3+28 = 31

--

2. Do inside brackets first.

5 [ 2 ( 8 + 5 ) - 15 ] = 5 [ 2 ( 13 ) - 15]

Multiply

5 [ 2 ( 13 ) - 15 ] = 5 [ 26 - 15 ]

Simplify bracket

5 [ 11 ] = 55

--

3. Simplify parentheses

14 / [ 3 ( 8 - 2 ) - 11] = 14 / [ 3 ( 6 ) - 11 ]

Multiply

14 / [ 3 ( 6 ) - 11 ] = 14 / [ 18 - 11 ]

Simplify

14 / [18 - 11 ] = 14 / [ 7 ]

14 / 7 = 2
