I need help.

Hey there!

Three basic rules determine this:

Positive Numbers are always greater than Negative Numbers.

If both are positive, the number with the greater magnitude is larger.

If both are  negative, the number with the smaller absolute value is larger.

Let me know if this helps :)

23x15=23x(10+5)                     Method 1 and 5

=23x10+23x5

=230+115

23x15=(20+3)x15                      Method 2

=20x15+3x15

=300+45

23x15=(20+3)x(10+5)

   =20x10+20x5+3x10+3x5      Method 3 and 6

=200+100+30+15
