@ktnguyen1 how did ya get it
OpenStudy (anonymous):
now the greater value is -32 so the greater value has to have the same exponenent as the answer

let me get this straight. two negative is a positive right
OpenStudy (anonymous):
both are not negatives
OpenStudy (anonymous):
one is -32 and the other is +29
OpenStudy (anonymous):
that means we add the two numbers but keep the bigger number's sign
OpenStudy (anonymous):

yes excacly
OpenStudy (anonymous):
oh sorry
OpenStudy (anonymous):
+ x - = -
OpenStudy (cwrw238):
2 negatives make a positive ehen multiplying eg -2 * -2 = +4
or in the a case like 2 - (-4) = 2+ 4 = 6
but -4 -6 = -10
or (-4)-6 = -10
