Question

How would I solve this?: |-2.8| + |2.8|

Answer 1

anything in the absolute value signs would turn positive
so |-2.8| = 2.8

so you can get 2.8 + 2.8 = ?

Answer 2

ok so no matter if its positive or not it will always be positive if it's in the "| |"

Answer 3

yes :)

Answer 4

so 5.6

Answer 5

correct ^_^

Answer 6

can you help with one more?

Answer 7

of course :)

Answer 8

oops

Answer 9

5 - [ -(-2) ]

Answer 10

lol yeah, they were having some copy paste issues with fancy characters...

know that negative times negative = positive
and positive times negative = negative

Answer 11

so would the [-(-2) ] be -2?

Answer 12

mmm -(-2) = +2
then -[-(-2)] = -[+2] = -2

Answer 13

so 5 - (-2)?

Answer 14

not quite
the stuff inside the outer parenthesis turns into -(-2) = +2
so you get 5 - (+2) =

Answer 15

7?

Answer 16

not quite, try again
5 - (+2) = 5 - 2 = ?
what's 5 minus 2 ? :3

Answer 17

ooh duh, I was adding the 5 and 2 xD ok cool thanks soo much :)!

Answer 18
