Answer 3

To calculate the value of the expression 2002 * 1998 - 2001 * 1999, follow the order of operations, which is typically represented by the acronym PEMDAS:

1. Parentheses (simplify expressions inside parentheses)
2. Exponents (perform operations involving exponents)
3. Multiplication and Division (perform these operations from left to right)
4. Addition and Subtraction (perform these operations from left to right)

In this case, there are no parentheses or exponents, so we'll proceed with multiplication and subtraction:

2002 * 1998 - 2001 * 1999

Step 1: Multiply the numbers:

2002 * 1998 = 3,991,996 2001 * 1999 = 3,998,199

Step 2: Subtract the results:

3,991,996 - 3,998,199 = -6,203

So, 2002 * 1998 - 2001 * 1999 equals -6,203.
