**58.378 × 0.396**

**Place one number beside the other with the multiplication symbol between them. Draw a line under the numbers. Temporarily disregard the decimal points and multiply the numbers like you would multiply integer numbers.**

__58.378×0.396__

**Multiply the number 58378 by the digit 3 and place the answer below the line. Write the answer in such way that the last digit be lined up with digit being multiplied of the second number.**

Multiply the digits 3 and 8 (3 × 8 = 24).

This number is larger than 9, so place the 2 above the column on the left to be added in the next step and place the 4 below the line.
