Question

|-2|+|-3.4|-|-9|=??

Answer 1

keep in mind that absolute values are ALWAYS positive

Answer 2

|-a| + |-b| is really the same as a + b once out of the bars

Answer 3

I keep on getting 14.4 but the answer is -3.6

Answer 4

Its absolute value so it is 2+ 3.4-9. So 2+3.4 is 5.4, and then subtract 9 from it and get -3.6!

Answer 5

You put the 9 as being add instead of keeping that minus sign. That's what got you!

Answer 6

once you take out the bars, the value becomes positive
the sign OUTSIDE the bars, remains the same

Answer 7

but i thought 2 negatives equal a positive?

Answer 8

Yes but that is in certain cases. It was just straight-forward, you didn't need to do that. Besides, usually these on state tests are multiple choice, so you can eliminate the obvious ones and follow the rules you've learned.

Answer 9

The Absolute Value bars separate it from being positive.
