Question

Math experts plzzz help!!Which operation should be performed first according to the order of operations?

117 + 45 – 34 • 8 + 36 ÷ 12 – 12

A.
34 • 8

B.
36 ÷ 12

C.
117 + 45

D.
45 – 34

Answer 1

"Order of Operations" rules are summed up in "PEMDAS." Do any work inside parentheses first, followed by any exponentiation, followed by multiplication or division, ending finally with addition or subtraction. Review this, please, and then apply these rules to the expression you've posted.

Answer 2

@mathmale I don't know where the parentheses are in this equation ;-;

Answer 3

there are none so go on

Answer 4

No exponent either....?

Answer 5

so go on

Answer 6

When there are no grouping symbols begin by doing all multiplications and divisions in order from left to right.

Answer 7

oops

Answer 8

backspaced.

Answer 9

34 x 8 = 272
Next..?

Answer 10

36 divided by 12 = 3

Answer 11

I don't get it

Answer 12

We need to read the problem more carefully

Which operation should be performed FIRST according to the order of operations?

117 + 45 – 34 • 8 + 36 ÷ 12 – 12

The operation that should be performed first is 34 • 8 because it is the first multiplication on the left.

Answer 13

Yes, I agree with that. We have 117+45 occurring before the first multiplication, which is -34*8. Just write out 117 + 45 - (product of 8 and 34). Next, divide 12 into 36, writing the result as +3. Finally, subtract that 12.

Then you'll need to combine, through addition and subtraction, what's left. NO more mult. or div.

Answer 14

And yes, you can carry out these + and - operations from left to right, although there's no law that says you must do so.
