Answer
Activity 1
1.) 223 x 22
= (200 + 20 + 3) x ( 20 + 2)
= (200 + 20 + 3)x 20 + (200 + 20 + 3)x 2
= 4, 000 + 400 + 60 + 400 + 40 + 6)
Final Product = 4, 906
2.) 123 x 21
= (100 + 20 + 3) x (20+ 1)
= (100 + 20 + 3) x20 + (100 + 20 + 3) x 1
= 2, 000 + 400 + 60 + 100 +20 + 3
Final Product = 2, 583
3.) 322x 12
= ( 300 + 20 + 2) x (10+2)
= ( 300 + 20 + 2) x10 + ( 300 + 20 + 2) x 2
= 3,000 + 200 + 20 + 600 + 40 + 4
Final Product = 3, 864
4.) 302 x 11
= (300 + 0 + 2) x (10 + 1)
= (300 + 0 + 2) x10 + (300 + 0 + 2) x 1
= 3, 000 + 0 + 20 + 300 + 0 + 2
Final Product = 3, 322
5.) 113 x 32
= (100 + 10 + 3) x (30+2)
= (100 + 10 + 3) x 30 + (100 + 10 + 3) x 2
= 3,000 + 300 + 90 + 100 + 10 + 6
Final Product = 3, 506
