What is 4+5x5-2?

The expression you've provided is a simple arithmetic expression: (4 + 5 \times 5 - 2). To solve this, you need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

Using PEMDAS:

1. Multiplication comes before addition and subtraction, so first calculate the multiplication: [ 5 \times 5 = 25 ]

2. Substitute this back into the expression: [ 4 + 25 - 2 ]

3. Now, perform the addition and subtraction from left to right: [ 4 + 25 = 29 ]

4. Then subtract: [ 29 - 2 = 27 ]

So, the result of the expression (4 + 5 \times 5 - 2) is 27.
