Textbook Problem

Estimate the following by rounding each number all the way; then multiply to get the exact answer.

To determine

**To calculate:** The rounded estimate and the exact answer of the multiplication,

Explanation

**Given Information:**

The provided multiplication is,

**Formula used:**

Steps for multiplying whole numbers.

Step 1: Write down the factors in columns such that the place values line up.

Step 2: Multiply every digit of the multiplier with the multiplicand, starting with the units. Each multiplication gives a partial product whose unit digit appears under the corresponding digit of the multiplier.

Step 3: Now in each column, add the digits of the partial products, starting with the units column on the right.

**Calculation:**

Consider the provided expression,

To find exact value of multiplication,

Remove the zeros and add them later in the final solution.

Multiply the multiplier â€˜9â€™ with the multiplicand.

Multiply the multiplier â€˜4â€™ with the multiplicand, and write the partial product under the corresponding column:
