Answer 4

Oh, ok. I see what you're doing 27/9=3+18=21

Answer 5

\[18+21/3^{2}\]\[18+21/9\]\[18+3\]

Answer 6

was that the correct way of solving

Answer 7

Yeah. I thought it was \[\frac{ 18+27 }{ 3^{2} }\]but that's not the equation. So yes, 21 is the right answer.

1over 2 - 7 over 8 = - 3 over 8

Answer 10

Answer 11

You're right. 21 is the right answer. 3^2=9.
27/9=3. Then 18+3=21

Answer 12

It depends if your question is \[\frac{ 18+27 }{ 3^{2} }~~~or~~~18+\frac{ 27 }{ 3^{2} }\]

Answer 13

The problem should be written like this:
18 + ( 27/9) should equal 21
18 + 3 should equal 21
21 does equal 21
