Question

45-19×25+10= ) математика 5 кл​

Answer 1

45-19*25+10=45-475+10=-430+10=-420

Answer 2

To solve this mathematical expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). According to PEMDAS, multiplication and division should be done before addition and subtraction.

Let's solve the expression step by step:

1. Start with multiplication: 19 × 25 = 475

2. Now, substitute the multiplication result back into the expression: 45 - 475 + 10

3. Perform addition and subtraction from left to right: 45 - 475 + 10 = -430 + 10 = -420

Therefore, the result of the expression 45 - 19 × 25 + 10 is -420.
