Guidance on solving Exercise 2 Page 46 Math Book Grade 4

Problem:
Calculate using the most convenient method:
a) 96 + 78 + 4 b) 789 + 285 + 15
67 + 21 + 79 448 + 594 + 52
408 + 85 + 92 677 + 969 + 123

Solution Method:
- Group the terms in the given expression into groups with sums that are multiples of ten/hundred.
- Apply the associative property of addition: When adding a sum of two numbers with a third number, we can add the first number with the sum of the second and third numbers.

Answer:
a) 96 + 78 + 4 = (96 + 4) + 78 = 100 + 78 = 178
67 + 21 + 79 = 67 + (21 + 79) = 67 + 100 = 167
408 + 85 + 92 = (408 + 92) + 85 = 500 + 85 = 585
b) 789 + 285 + 15 = 789 + (285 + 15) = 789 + 300 = 1 089
448 + 594 + 52 = (448 + 52) + 594 = 500 + 594 = 1 094
677 + 969 + 123 = (677 + 123) + 969 = 1 769
