4th Grade Math Expressions

Introduction to 4th grade math expressions:

4th grade math expressions deals with the simple  format of expressions containing variable, the variables are in the form of alphabetic, such as x, y, z, m, n… Using this we can create and expressions which is in the equation form and find the value of variables.

Addition, subtraction, division, and multiplication are called basic arithmetic operations of mathematics which are performed on 4th grade math expressions. This article shows the different operations performed on 4th grade math expressions.

I like to share this Dividing Rational Expressions with you all through my article.

Examples problem for 4th grade math expressions:


1. Find the x value for given expression, x + 7.

Solution:

Given expression is,

x + 7 = 0

Both sides subtracting by -7,

x + 7 – 7 = -7

Simplify the values,

Then we get the answer is,

x = -7

The answer to variable x is -7.

2. Find the z value for given expression, z + 3.

Solution:

Given expression is,

z + 3 = 0

Both sides subtracting by -3,

z + 3 – 3 = -3

Simplify the values,

Then we get the answer is,

z = -3

The answer to variable z is -3.

3. Find the y value for given expression, y +17.

Solution:

Given expression is,

y + 17 = 0

Both sides subtracting by –17,

y + 17 – 17 = -17

Simplify the values,

Then we get the answer is,

y = -17

The answer to variable y is -17.

4. Find the x value for given expression, x - 5 -13 + 4.

Solution:

Given expression is,

x - 5 -13 + 4 = 0

First combine the integers,

x - 5 -13 + 4 = 0                          (-5 -13 + 4 = -14)

x -14 = 0

Both sides adding by 14,

x - 14 + 14 = 14

Simplify the values,

Then we get the answer is,

x = 14

The answer to variable x is 14.

5. Find the y value for given expression, y - 2 - 3 + 4.

Solution:

Given expression is,

y - 2 - 3 + 4 = 0

First combine the integers,

y - 2 - 3 + 4 = 0                          (-2 -3 + 4 = -1)

y -1 = 0

Both sides adding by 1,

y - 1 + 1 = 1

Simplify the values,

Then we get the answer is,

y = 1

The answer to variable y is 1.

6. Find the z value for given expression, z - 4 -10 + 24.

Solution:

Given expression is,

z - 4 -10 + 24 = 0

First combine the integers,

z - 4 -10 + 24 = 0                          (-4 -10 + 24 = 10)

z +10 = 0

Both sides adding by -10,

z + 10 - 10 = -10

Simplify the values,

Then we get the answer is,

z = -10

The answer to variable z is -10.

7. Find the x value for given expression, x - 25 -10 + 20.

Solution:

Given expression is,

x - 25 -10 + 20 = 0

First combine the integers,

x - 25 -10 + 20 = 0                          (-25 -10 + 20 = -15)

x -15 = 0

Both sides adding by 15,

x - 15 + 15 = 15

Simplify the values,

Then we get the answer is,

x = 15

The answer to variable x is 15.
