A = #2#

First, let's create a list of square number and the number being squared to achieve the square number:

#1 * 1 = 1#
#2 * 2 = 4#
#3 * 3 = 9#
#4 * 4 = 16#
#5 * 5 = 25#

Thus, just list and then identify the square number.

All the best!

#2# or #-2#

#(2)(2)=4#
#(-2)(-2)=+4#

A negative number multiplied by another negative number results in a positive number.

negative x negative = positive
