Can you describe multiplying and dividing signed numbers in the real world??

Answer 1

Ordering pizza.

So one large pizza costs 5.00 and since I want three of them, 5 x 3 = 15. I'll be paying 15 dollars for 3 large pizzas

Answer 2

What about the signed numbers part?

Answer 4

I assume that signed numbers means you're dealing with numbers that have a plus or minus sign attached to them?

Answer 5

Yes

Answer 6

So I assume this example would do:

You have $100 in your bank account. You and your friend want to purchase something that cost's $120.

You draw $120, and divide the debt with your friend. You both have -$10 / Owe the bank $10

Answer 7

ok remember these rules->
+ve ---> a positive number
-ve--> a negative number

multiplication rules-
\[(+ve) \times (+ve)=+ve\]\[(+ve) \times (-ve)=-ve\]\[(-ve) \times (+ve)=-ve\]\[(-ve) \times (-ve)=+ve\]
division rules-\[\frac{ +ve }{ +ve }=+ve\]\[\frac{ +ve }{ -ve }=-ve\]\[\frac{ -ve }{ +ve }=-ve\]\[\frac{ -ve }{ -ve }=+ve\]

or u can just remember this-
whenever u have 2positives or 2negatives in a multiplication or division then u always get a positive number

but if u have a positive and a negative then u will always get a negative number
