Answer 2

To solve the expression 21•56•4-234+551-111•943•241, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

1. Multiplication and Division: - 21•56•4 = 21 * 56 * 4 = 4,704 - 111•943•241 = 111 * 943 * 241 = 25,091,913

2. Subtraction: - 4,704 - 234 = 4,470

3. Addition: - 4,470 + 551 = 5,021

4. Subtraction: - 5,021 - 25,091,913 = -25,086,892

Therefore, the result of the expression 21•56•4-234+551-111•943•241 is -25,086,892.
