Dear S1-07

Some of you gave feedback that the "Explanation in words" for Q7 is not clearly scanned.

Here's the responses:

(a) The order of operation is incorrect. When there is only x (multiplication) and ÷ (division) on the same line, we should work from left to right.

(b) -3^2 should be -9 as we are only squaring "3".

Square root of (16/25) should be 4/5. The square root applies to both numbers on the numerator and denominator.

Recall that: The set of solution is available in the GoogleSite.
