Operations of absolute numbers

Substitute the values for a and b to find the value below:
a = 6, b = -4
| a + 2b | = ___

Answer explanation

| 6 + 2(-4) | = | 6 - 8 |
= | -2|
= 2

Substitute the values for a and b to find the value below:
a = 6, b = -4
| a - 2b | = ___

Answer explanation

| 6 - 2(-4) | = | 6 + 8 |
= | 14 |
= 14

Substitute the values for a and b to find the value below:
a = 6, b = -4
| -2a + b | = ___

Answer explanation

| -2(6) +(-4) | = | -12 - 4 |
= | -16 |
= 16

Substitute the values for a and b to find the value below:
a = 6, b = -4
| -2a - b | = ___

Answer explanation

| -2(6) - (-4) | = | -12 + 4 |
= | -8 |
= 8

Substitute the values for a and b to find the value below:
a = 6, b = -4
| 3b - 3a| = ___

Answer explanation

| 3(-4) - 3(6) | = | -12 - 18 |
= | -30 |
= 30

Substitute the values for a and b to find the value below:
a = -5, b = -2
| b³ | = ___

Answer explanation

| (-2)³ | = | -8 |
= 8

Substitute the values for a and b to find the value below.
a = -7 , b = 2.
a + | a +b | = ___

Answer explanation

a + | a +b | = -7 + | -7 + 2|
= -7 + |-5|
= -7 + 5
= -2

Substitute the values for a and b to find the value below.
a = -7 , b = 2.
a + | a | + b + | b | = ___

Answer explanation

a + | a | + b + | b | = -7 + | -7| + 2+ |2|
= -7 + 7 + 2 + 2
= 0 + 4
= 4
