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.

Hi, thanks for your reply,
The final answer is 22 and not 2, if I put a minus, followed by a divide. Pls clarify pls.
many thanks

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
