How do you do absolute value?????

Question

examples
1.[ -124 ]
2.[ -31+15 ]
3. - [ 8+9-21]

Answer 1

the easiest way, if youre having trouble understanding absolute values, is to do any arithmetic (if necessary) within the | |'s and take the most positive number (in other words, if there is a negative sign, drop it).

1. |-124| = 124 (drop the negative sign)
2. |-31+15| = |-16| = 16 (compute first, then drop sign)
3. -|8+9-21| = -|-4| = -4 (here, the negative sign on the OUTSIDE does not come in to play until the very end. Notice how we compute first, and |-4| = 4 by dropping the sign, but then applied the outside negative sign at the end.

Answer 2

you are using brackets and not absolute vallue bars.

[ - 124 ] = - 124

∣- 124∣= 124. . .Absolute balue

- - - - - - -

[ - 31 + 15 ] =

[- 15 ] = - 15

∣- 31 + 15∣=

∣- 16 ∣= 16. . .Absolute value

- - - - - - - -

- [ 8 + 9 - 21] =

- [ 17 - 21 ] =

- [ - 5] = 5

-∣8 + 9 - 21∣=

- ∣17 - 12∣=

- ∣- 5 ∣ =

- 5. . .Absolute value

Answer 3

You perform your normal operations on items within the brackets. Then convert that value to a positive value as indicated by the brackets.Then perform outside operations. In answer number 3 the outside operation is indicated by a minus sign to negate the number.

Answer 4

Absolute value is just the magnitude of the distance of the point from 0 i.e abs(-1) = abs(1) = 1

1. abs(-124) = 124
2. abs(-16) = 16
3. abs(-4) = 4

Answer 5

gebobs' answer on #3 shoudl be -4, not +4. The negative sign in front of everything will negate the absolute value. Otherwise, he is correct.

Answer 6

1. I-124I = 124
2. I-31+15I = I-16I = 16
3. - I8+9-21I = - I-4I = -4
