Solving Mathematical Expressions with PEMDAS/BODMAS

Solving mathematical expressions correctly involves adhering to the order of operations, commonly represented as PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication (from left to right), Addition and Subtraction). In this article, we will explore various expressions and solve them using these rules.

Expression: 20/52

To solve the expression 20/52, we follow the order of operations:

Divide: 20/5 4 Multiply: 4 * 2 8

Therefore, the solution is 20/52 8.

Expression: 8

The expression in this case is simply the number 8, and since there are no operations to perform, it remains as is. Thus, the answer is 8.

Expression: 20 ÷ 52

The expression in this case is 20 ÷ 52. Following the BODMAS rule:

Brackets: 2 * 2 4 Multiplication: 5 * 4 20 Division: 20 ÷ 20 1

Hence, the solution is 20 ÷ 52 1.

Expression: 20 ÷ (52 - 10)

For the expression 20 ÷ (52 - 10), we follow the BODMAS order:

Brackets: (52 - 10) 42 Division: 20 ÷ 42

The result is approximately 0.476.

Expression: 20 ÷ 522

For the expression 20 ÷ 522, we again follow the BODMAS order:

Multiplication: 5 * 4 20 Division: 20 ÷ 20 1

Hence, the solution is 20 ÷ 522 1.

Expression: X/5 22 ÷ 100

This expression can be solved as:

Multiplication: X/5 0.22 Multiplication: X 5 * 0.22 Multiplication: X 1.1

The solution to the expression is X 1.1.
