Division and Multiplication Flashcard

Front

What is multiplication?

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times: 3 + 3 + 3 + 3 = 12.

Front

What is division?

Back

Division is a mathematical operation where a number is split into equal parts. For example, 12 divided by 3 (12 ÷ 3) means splitting 12 into 3 equal parts, which equals 4.

How do you calculate the total cost of multiple items?

Back

To calculate the total cost, multiply the number of items by the cost of each item. For example, if one pencil costs 45 cents and you buy 678 pencils, the total cost is 678 x 0.45 = $305.10.

What is the formula for finding the number of packs from a total?

Back

To find the number of packs, divide the total number of items by the number of items per pack. For example, if you have 345 apples and want to pack them in packs of 23, you calculate 345 ÷ 23 = 15.

Front

How do you divide items equally among friends?

Back

To divide items equally, divide the total number of items by the number of friends. For example, if Madison has 954 stickers and 6 friends, she calculates 954 ÷ 6 = 159 stickers per friend.

Front

What is the process to distribute items evenly?

Back

To distribute items evenly, divide the total number of items by the number of groups. For example, if there are 432 apple slices and 6 plates, you calculate 432 ÷ 6 = 72 slices per plate.

Front

How do you calculate total sales from selling items?

Back

To calculate total sales, multiply the number of items sold by the price of each item. For example, if Malachi sold 567 toys at $32 each, the total sales are 567 x 32 = $18,144.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If you multiply a number and then divide by the same number, you return to the original number. For example, 4 x 3 = 12 and 12 ÷ 3 = 4.

Front

What does it mean to find the quotient?

Back

The quotient is the result of a division problem. For example, in the division 20 ÷ 5, the quotient is 4.

Front

What is a remainder in division?

Back

A remainder is what is left over after division when the numbers do not divide evenly. For example, in 10 ÷ 3, the quotient is 3 and the remainder is 1.
