Question

determine whether the following addition is correct or incorrect.
1214 + 1371 + 4111 = 6696
select the correct choice below and fill in the answer box to complete your choice.
a. the addition is incorrect because adding the numbers on the left side of the equation results in
. b. the addition is correct because adding the numbers on the left side of the equation results in
.

Explanation:

Step1: Add the first two numbers

First, we add 1214 and 1371. So, \(1214 + 1371 = 2585\).

Step2: Add the result to the third number

Next, we add the result from Step 1 (2585) to 4111. So, \(2585+4111 = 6696\)? Wait, no, let's recalculate. Wait, 2585 + 4111: 2585 + 4000 = 6585, then +111 = 6696? Wait, but let's check again. Wait 1214 + 1371: 1200 + 1300 = 2500, 14 + 71 = 85, so 2500 + 85 = 2585. Then 2585 + 4111: 2585 + 4000 = 6585, 6585 + 111 = 6696. Wait, but the right side is 6696. Wait, but maybe I made a mistake. Wait, 1214 + 1371: 1214 + 1371. Let's do digit by digit: units: 4 + 1 = 5; tens: 1 + 7 = 8; hundreds: 2 + 3 = 5; thousands: 1 + 1 = 2. So 2585. Then 2585 + 4111: units: 5 + 1 = 6; tens: 8 + 1 = 9; hundreds: 5 + 1 = 6; thousands: 2 + 4 = 6. So 6696. So the addition is correct? Wait, but let's check again. 1214 + 1371 = 2585. 2585 + 4111: 2585 + 4000 = 6585, 6585 + 111 = 6696. So the sum is 6696, which matches the right side. Wait, but maybe I miscalculated. Wait, 1214 + 1371: 1214 + 1371. Let's add 1214 + 1371: 1214 + 1371 = 2585. Then 2585 + 4111: 2585 + 4111. Let's add 2585 + 4111: 2585 + 4111 = 6696. So the addition is correct. Wait, but the options are A and B. So B is correct.

Wait, but maybe I made a mistake. Wait, let's check with another method. 1214 + 1371 + 4111. Let's add 1214 + 4111 first. 1214 + 4111: 1200 + 4100 = 5300, 14 + 11 = 25, so 5300 + 25 = 5325. Then 5325 + 1371: 5325 + 1300 = 6625, 6625 + 71 = 6696. Yes, so the sum is 6696. So the addition is correct. So option B is correct.

Answer:

B. The addition is correct because adding the numbers on the left side of the equation results in 6696.
