Multiplication & Division Including Multi-Step Problem Solving

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times (3 + 3 + 3 + 3) which equals 12.

Front

What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 divided by 3 (12 ÷ 3) means splitting 12 into 3 equal parts, which equals 4.

Front

How do you find the remainder in division?

Back

The remainder is what is left over after division when a number cannot be divided evenly. For example, in 29 ÷ 5, 5 goes into 29 five times (5 x 5 = 25) with a remainder of 4.

Front

What is a multi-step problem?

Back

A multi-step problem is a problem that requires more than one operation to solve. For example, first you might need to multiply, then add or subtract to find the final answer.

Front

If a farmer has 15 apple trees and each tree produces 30 apples, how many apples does he have in total?

Back

450 apples (15 x 30 = 450).

Front

If you have 36 apples and want to divide them into 6 baskets, how many apples will be in each basket?

Back

6 apples (36 ÷ 6 = 6).

Front

What is the formula for finding the total number of items when given groups?

Back

Total items = Number of groups x Items per group. For example, if there are 7 groups of 9 items, the total is 63 (7 x 9 = 63).

Front

How do you calculate how many groups can be formed from a total?

Back

To find how many groups can be formed, divide the total number of items by the number of items per group. For example, 29 students in groups of 5 gives 5 groups with 4 left over (29 ÷ 5 = 5 R4).

Front

What is the total number of toy cars left after selling some?

Back

To find the total left, first calculate how many boxes can be formed, then subtract the sold boxes from the total. For example, 45 toy cars in boxes of 5 gives 9 boxes. If 3 boxes are sold, 6 toy cars are left (45 - 15 = 30).

Front

What is the importance of understanding remainders in division?

Back

Understanding remainders helps in real-life situations where items cannot be evenly distributed, such as when forming groups or packing items.
