Grade 4 Math Skills Flashcard

Subtraction is the process of taking one number away from another. For example, in the equation 10 - 4 = 6, 4 is subtracted from 10, resulting in 6.

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

A fraction represents a part of a whole. It consists of a numerator (top number) and a denominator (bottom number). For example, in the fraction $$\frac{1}{2}$$ , 1 is the part and 2 is the whole.

The difference is the result of subtracting one number from another. For example, the difference between 10 and 4 is 6 (10 - 4 = 6).

The total is the sum of all the numbers added together. For example, if you add 2, 3, and 5, the total is 10 (2 + 3 + 5 = 10).

A meter is a unit of length in the metric system, equal to 100 centimeters.

A centimeter is a unit of length in the metric system, equal to one hundredth of a meter.

One half is represented as $$\frac{1}{2}$$ .

$$\frac{2}{4}$$ is an equivalent fraction of $$\frac{1}{2}$$ .

To convert meters to centimeters, multiply the number of meters by 100. For example, 2 meters = 2 x 100 = 200 centimeters.
