1. The problem is to find the sum of 48 and 126. 2. We add the two numbers: $$48 + 126 = 174$$. 3. So, the sum of 48 and 126 is 174. 1. Janice has 24 buttons and Stia has 29 buttons. 2. To find the total number of buttons, we add their amounts: $$24 + 29 = 53$$. 3. Therefore, Janice and Stia together have 53 buttons. 1. There were 42 marbles in one box and 73 in another. 2. To find the total number of marbles, add the two amounts: $$42 + 73 = 115$$. 3. Hence, both boxes have 115 marbles altogether. 1. Initially, there were 54 and 176 apples. Then 120 more apples were bought. 2. First find the total apples before buying more: $$54 + 176 = 230$$. 3. Then add the newly bought apples: $$230 + 120 = 350$$. 4. So now, there are 350 apples.
