Question

Match each addition operation to the correct sum.

0.65 more than 4.35:
1.98 added to 3.13:
4.34 added to 10-8:
9.14 added to -9.14:

Answer 1

To find the correct sums for each addition operation, we apply the rules of addition and sign conventions. The sums are: 5, 5.11, 6.34, and 0.

Step-by-step explanation:

To match each addition operation to the correct sum, we need to apply the rules of addition and follow the principles of sign conventions. Let's go through each operation one by one:

1.

0.65 more than 4.35

: Here, we need to add 0.65 to 4.35. The sum is 5 (4.35 + 0.65 = 5).

2.

1.98 added to 3.13

: We need to add 1.98 to 3.13. The sum is 5.11 (3.13 + 1.98 = 5.11).

3.

4.34 added to 10-8

: Adding positive and negative numbers follows the rule of subtracting the smaller number from the larger number and keeping the sign of the larger number. Here, 10 - 8 gives us 2, and when we add 4.34 to 2, the sum is 6.34 (2 + 4.34 = 6.34).

4.

9.14 added to -9.14

: Adding a positive number and a negative number with the same absolute value cancels out each other. So, the sum is 0 (9.14 + (-9.14) = 0).
