Hi,

I have been able to help my girl’s math till I hit this question on multiplication.

If (3) = 3 x 3 and (4) = 4 x 4, then,
(5) x (2) = ( )

Please note that the ( ) is actually a square box. I do not know if the box is significant or not and can’t keep wonder if this is a IQ question or printing error.

Anyone have any idea ? This is one of the school worksheet in multipication.
Thanks

(5) = 5 x 5 = 25

(2) = 2 x 2 = 4
(5) x (2) = 25 x 4 = 100

or may be

(5) x (2) = (10) = 10 x 10 = 100

my guess
