Hi, can someone clarify on this question? I can't seem to get the answer!

Q30 : Fill in the blanks [ ] below with different operations (+, -, x, ÷) to make the mathematical statement correct.
Each operation is used onced only.

24 [ ] (6+6) [ ] 6 = 22

Thanks

Hey there,

its Minus , followed by Divide as follows:

24 [ - ] (6+6) [ ÷ ] 6 = 22

==============

Hope this helps.

Cheers,

The final answer is 22 and not 2, if I put a minus, followed by a divide. Pls clarify pls.

Under of Order of Operations, <BRACKET> comes before <DIVIDE> comes before <MINUS>. In this kind of question, its not necessary that you do from LEFT to RIGHT. You have to follow the rules under Order of Operations.

So (6+6) = 12; then (12 ÷ 6) = 2; then (24 - 2) = 22

Does this help clarify?

Cheers,
Edward
