ADDING MORE THAN TWO NUMBERS WITH REGROUPING

Rani’s father refers an online shopping store app to Rani and

her sister. Rani shopped online and gained 4 points. Her sister
shopped at the same online store and gained 5 points. Their
father gained 6 referral points without shopping.

Rani: How many points have we earned altogether?
Father: 4 + 5 + 6 = 15 points

Rani: How do you add so quickly? Check if the
Father: We can add more than two sum of any two T O
numbers in any order. Group the numbers is 10. 4

numbers to make tens. We know that 5
4 and 6 make 10, so we can add them + 6
together first. Then we add 5 to 10. 1 5

Thus, 4 + 5 + 6 = 4 + 6 + 5 = 10 + 5 = 15
