Reminder about myself• Hello people! I'm going to tell you about myself. First of all I'm zero,
which isn't a positive or a negative. My friends are positives and negatives though..let me tell you about them though.
• Multiplication - when you multiply integers with same sign, do normal multiplication and the sign of the answer is positive 3 x 4 = 12
• When you multiply integers with opposite sign, do normal multiplication and the sign of the answer is positive (-3) x (-4) = 12
• When you multiply integers with opposite signs, do normal multiplication and the sign of the answer is negative 3 x (-4) = -12
• (-3) x (4) = -12 -the rules in multiplication are the same rules applying to division, except of course you have to change the sign to division.
• And me well...im zero. Zero is never negative or positive so yeah....Bye!
RULES
