Question

Sort the following in descending order.

• A. 3 x 4
• B. 3 x (-4)
• C. (-3) x (-5)
• D. -6 x 3
• E. -5 x 6

Answer 1

If both the numbers that are being mulitplied have same sign, then product will have positive sign else if, the numbers being multiplied have different signs then product will have negative sign. So,
$3\times 4=123\times (-4)=-12-3\times (-5)=15-6\times 3=-18-5\times 6=-30$

Descending order of the solution is
15 > 12 > -12 > -18 > -30.

$\therefore$ Descending order of the given expressions are (-3) x (-5) > 3 x 4 > 3 x (-4) > (-6) x 3 > (-5) x 6.
