ference. Fasten an arrow loosely in the center. Each child spins the arrow, multiplies the number to which the arrow points by a given number, and adds a second given number. For example, one child spins, multiplies the indicated number (say 9) by 6 and adds 5; another child spins and multiplies 12 by 6 and adds 5.

In practice the 0 in the second partial product is omitted, and 1280 is written as 128 tens by placing the right-hand figure of that product in tens' place.

The number multiplied is called the multiplicand. The number showing how many times the multiplicand is taken is called the multiplier.

The result in multiplication is called the product.

When multiplying by 3 hundreds, write the partial product as 2082 hundreds by placing the first figure of that product under hundreds.

Do not write the naughts in units and tens in the second partial product, as in the first illustration.

When multiplying by 3 hundred, write the partial product as 819 hundreds by placing the right-hand figure of that product in hundreds' place.

4. Use as the multiplier the number that will re

quire fewer partial products.
