Solve the following:

i. 345,678 + 123,456 - 98,765

ii. 765,432 - 234,567 + 456,789

Let's solve each part of the question step-by-step to make sure we understand the process of addition and subtraction.
i. 345,678 + 123,456 - 98,765

First, we perform the addition: 345678 + 123456 = 469134

Now, we subtract: 469134 − 98765 = 370369


So, the answer to the first part is: 370,369.
ii. 765,432 - 234,567 + 456,789

First, we perform the subtraction: 765432 − 234567 = 530865

Now, we add: 530865 + 456789 = 987654


So, the answer to the second part is: 987,654.
By breaking down the operations step-by-step, it is easier to follow the calculations and ensure that each part is accurate. Understanding how and why we perform each operation helps solidify the concepts of addition and subtraction.
