Create three different expressions that are each equal to 20. Each expression should include only these three numbers:

4
-2
10

Answers

First expression: 10-4(4/(-2))+2 = 20
Second expression: 10x4-10x(-2) = 20
Third expression: 10-4(-2)+2 = 20

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The three expressions that use only 4, -2, and 10 and that are equal to 20 are:

4 x 2 - (-2) + 10

4 x 10 + (-2) x 10

-2 x (-2) + 4x4

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

We have,

20

The three expressions that are equal to 20 using only 4, -2, and 10 are:

First expression:

4 x 2 - (-2) + 10

= 8 - (-2) + 10

= 8 + 2 + 10

= 20

Second expression:

4 x 10 + (-2) x 10

= 40 - 20

= 20

Third expression:

-2 x (-2) + 4x4

= 4 + 16

= 20

Thus,

The three expressions that use only 4, -2, and 10 and that are equal to 20 are:

4 x 2 - (-2) + 10

4 x 10 + (-2) x 10

-2 x (-2) + 4x4
