Question

10 + 10 + 10 + 10 + 10 = ?

90 + 90 + 90 + 90 + 90 = ?

Answer 1

10 + 10 + 10 + 10 + 10
= 20 + 10 + 10 + 10
= 30 + 10 + 10
= 40 + 10
= 50
10 + 10 + 10 + 10 + 10
= 10 . 5
= 50
 

90 + 90 + 90 + 90 + 90
= 180 + 90 + 90 + 90
= 270 + 90 + 90
= 360 + 90
= 450
90 + 90 + 90 + 90 + 90
= 90 . 5
= 450
