Fourth Grade Math Expressions

Introduction to fourth grade math expressions:

Fourth grade math expressions involve the process of solving basic math expressions using arithmetic symbols. The algebraic expressions with arithmetic symbols are referred as fourth grade math expressions. For fourth grade students, the simple math expressions include addition, subtraction, division and multiplication. The elementary math expressions are solved for fourth grade students. The following are the example math expressions with detailed solutions for fourth graders.

Fourth Grade Math Expressions Examples:

Fourth grade math expressions are divided into four sections as Basic Math Operation, Fractions, Integers Operations, Combining like terms of Variables. The example problems are discussed below with step by step detailed solution for fourth graders. The solved problems are under arithmetic categories.

Basic Math Operations:

Fourth grade math expressions mainly cover addition, subtraction, multiplication, and division problems

1) Solve, 3(4+3) – 9 + 3(4)

Solution:
= 3(7) – 9 + 12
= 21 + 3
= 24

2) Solve, 5 + `8/4` * 5 + 5

Solution:
= 5 + 2 * 5 + 5
= 5 + 10 + 5
= 20

3) Solve, 6^2 + 7^2  

Solution:

= (6 * 6) + (7 * 7)
= 36 + 49
= 85

Fractions:

Fraction is one of the parts of fourth grade math expressions. Simplify the following (Write in mixed number if any of the answer is an improper fraction)

1) Solve` (2/3) + (1/5)`

Solution:

Take LCM as 15
= `(10/15) + (3/15)`

Add the above terms.
` = (10+3) / 15 `

` = 13/15`

2) Solve` (3/5) - (1/6)`

Solution:

Take LCM as 30
` = (18/30) - (5/30)`

Add the above terms.
=` (18 - 5) / 30`


=` 13/30`

Integer Operations:

Integer operation deals with performing math operations with integers such as positive and negative integers.

1) Solve, 11(–7)
= – 77

2) Solve, –81 / –3
= –27 / –1
= 27

3) Solve, –14 – (–3)
= –14 + 3
= –11

Variables – Combining Like Terms:

Variables plays major role in fourth grade math. Simplifying variables by combining like terms helps to calculate the value of the variable.

1) Solve, 5x + 3 – 3x
= 5x – 3x + 3
= 2x + 3

2) Solve, y + 2y – 2 + 5
= 3y + 3
