Math Question: What is the value of the expression (6 × 1000) + (5 × 100) + (4 × 10) + (3 × 1)?

To calculate the expression, we can multiply the digit in each place value by its corresponding power of 10 and add them up. So we have: (6 × 1000) + (5 × 100) + (4 × 10) + (3 × 1) = 6000 + 500 + 40 + 3 = 6543. Hence, the value of the expression is 6543.

What is the sum of the digits in the number 6543 when each digit is multiplied by its respective place value and added together?

To find the sum of the digits in 6543, we multiply the thousands digit (6) by 1000, the hundreds digit (5) by 100, the tens digit (4) by 10, and the units digit (3) by 1. Adding all these products, we get (6 × 1000) + (5 × 100) + (4 × 10) + (3 × 1) = 6000 + 500 + 40 + 3 = 6543. Thus, the sum of the digits in 6543 is 6 + 5 + 4 + 3 = 18.

Math question: Consider the number 6543. Evaluate the expression (6 × 5) + (4 × 3) - 543.

To solve the expression, we first simplify within the parentheses, making it (30) + (12) - 543. Then, we perform the multiplication and addition, resulting in 42 - 543. Lastly, we do the subtraction, resulting in -501. Therefore, the answer to the math question is -501.
