CHAPTER IV.

MULTIPLICATION.

EXAMPLE FOR THE BOARD.

If a barrel of flour costs $4.75, what will 4 barrels cost?

4 Multiplier.

19.00 Product.

The answer may be obtained as in (1), by addition. But as the same figures are repeated 4 times, the sum of each column may be readily found by multiplication, as in (2). We say, 4 times 5 hundredths are 20 hundredths, or 2 tenths and 0 hundredths; 4 times 7 tenths are 28 tenths, and 2 tenths to carry are 30 tenths, or 3 units and 0 tenths; 4 times 4 units are 16 units, and 3 units to carry are 19 units.
