"ABC Basic Mathematics Short-Cuts Of Base-10 Math"

For Example: 12 x 18. Find the partial products and the product.

Problem- # 1
B x A = C

A 18

B 12

C 216

Pictorial Solution: Base-10 Method - # 1
Multiplier 12 x 18 Multiplicand

18

(12 = 10 + 2) x10 + 2

( 180 + 36 ) = ( 216 )

(or) (180 + 20 + 16 ) = ( 216 )

Partial Products and Product

Written Solution: (It is as simple as A B C.)

First Step - Separate the Base-10 Number (10) from the multiplier which is (12) = (10 + 2); thus (10 + 2) becomes the multiplier for the problem (12 x 18).

Second Step - Multiply (10 x 18) = (180) the partial product.

Third Step - Multiply (2 x 18) = (36) the partial product, or multiply (2) x (10 + 8) = 36; and then add the partial products (180 + 36) = (216) the product.
