We can multiply bigger numbers using an algorithm!

2
Calculate 50 X X53 Calculate 50 X ,000 Calculate 3 X 60 Calculate 3 X 7 + Add the results 3,551 To find 67 x 53, decompose the numbers! Think of 67 as Think of 53 as Multiply each part of 67 by each part of 53. Add the results Always start here

3
Calculate 40 x X45 Calculate 40 x ,200 Calculate 5 x 80 Calculate 5 x 2 + Add the results 3,690 Let’s try another one! Always start here

4
= 10 x X18 = 10 x = 8 x 20 = 8 x 6 + Add the results 468 Try this on your own!

5
81 X53 Let’s try one more!
