2. Multiplication And Division By: Andrew

3. Multiplication Multiplication is like 9 nine times, like in 9×9. So, say you where at the store. You want to buy 12 cans of pop. You can get 2 six-packs or 1 twelve pack. A twelve pack is $6 and the 6 packs are $2. Which is the better answer? How to solve with multiplication 2 six packs- $2×2=$4 1 twelve pack=$6 That shows that 2 six packs is the better price.

4. Division Division is dividing a number into a certain number of groups. So, say you ordered 6 pizzas. You cut each of them in fourths. Now you have 24 fourths of a pizza. You invited 5 people. Each person (including you) is expected to eat 2 fourths. Did you buy enough? How to solve with Division 24 fourths divided by 6 people equals 4 fourths, so you bought WAY to much. Division algorithms Partial Quotients

5. DivisionMultiplication Relations and Differences  1 algorithm  Number goes down.  Similar to other math. operation, subtraction.  2 algorithms  Number usually goes up  Similar to other math operation, addition.
