Evaluating the Expression: 1+2x3-4+5
Evaluating mathematical expressions can sometimes be a daunting task, especially when we have multiple operations involved. In this article, we will break down the expression 1+2x3-4+5
step by step and evaluate it.
Order of Operations
Before we start evaluating the expression, it's essential to remember the order of operations. The order of operations is a set of rules that dictates the order in which we perform mathematical operations when there are multiple operations in an expression. The acronym PEMDAS is commonly used to remember the order:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Evaluating the Expression
Now, let's evaluate the expression 1+2x3-4+5
step by step:
Step 1: Multiply 2 and 3
2x3 = 6
So, the expression becomes:
1 + 6 - 4 + 5
Step 2: Evaluate the Addition and Subtraction Operations
Now, we need to evaluate the addition and subtraction operations from left to right:
1 + 6 = 7
7 - 4 = 3
3 + 5 = 8
Final Answer
Therefore, the final answer is:
8
In conclusion, the evaluated expression 1+2x3-4+5
is equal to 8.
