-8(-6) - (-7)(9) + 42/(-7) please help
Well do the multiplication first
Is this order of operations?
yes
Well do PEDMAS Parentheses Exponents Multiplication Subtacrtion (left to right) Addition (Left to right)
I have tried doing the problem on my own and they t urn out to be the wrong answers
ok well first off what is -8(-6)?
hint: - times a minus equals a positive
a positive 48?
and then -7(9) is -63... so then what would be next?
Good job!
so then I put 48-(-63)= 111 then 111+42= 153 so then the next step is where I got stuck!!
Yes, good job. Alright the next step is hold on and let me look ;)
48-(-63) is equal to 48+63 because 5--5= 5 plus ten, five minus a minus five equals a postive ten
Alright then you have 111+ 42/-7 (which is...)
Solve that. Then add up the total foryour answer.
Does that make sense? :)
-8(-6) - (-7)(9) + 42/(-7) I did the multiplication first, then the rest i got 105
kit kat that's what I didn't understand... is that suppose to be division or a fraction?
the 42/ (-7) ??
Katheryn that is 42 divided by -7 which becomes -6
i got 105
(-7)*(9) evaluates to -63 -8*(-6)-(-7)*(9) evaluates to 111 Because of the minus sign 7 becomes - 7 The answer is -7 42/(-7) evaluates to -6 -8*(-6)-(-7)*(9)+42/(-7) Final answer 105
