Answer 3

To solve this arithmetic expression using a table or "long division" method, you can follow these steps:

1. Write the dividend (2928) inside the division bracket and the divisor (142) outside the bracket, with a line separating them.

      _______
 142 | 2 9 2 8

2. Starting with the leftmost digit of the dividend, divide it by the divisor and write the quotient (result of division) above it. Then multiply the quotient by the divisor and write the product below the first digit of the dividend. Subtract the product from the first digit of the dividend to get the remainder (what's left over).

         448

3. Bring down the next digit of the dividend (8) next to the remainder to form a new two-digit number. Repeat the division process by dividing the new number by the divisor and writing the quotient above it. Multiply the quotient by the divisor and write the product below the new number. Subtract the product from the new number to get a new remainder.

4. Bring down the next digit of the dividend (2) next to the remainder to form a new two-digit number. Repeat the division process as before to get a new quotient, product, and remainder.

5. If there are no more digits to bring down, and the remainder is zero, then the division is complete. The final quotient is the result.

             8  0

Therefore, (2928-88)÷142 = 20 + 2/142 + 0/142^2 + 8/142^3 = 20.0208 (rounded to four decimal places).
