In the addition problem at the bottom, the sum of the two digits represented by B and C is ?. Each time the same letter appears it represents the same digit) 2BA
+C6D____
8AD
2BA
C6D
-----
8AD
since A+D=D, A=0
so, B+6=10, and B=4
so, 2+C+1=8, so C=5
B+C=9
I just understand.........
Don't clearly...
To find the sum of the two digits represented by B and C, you will need to solve the addition problem.
The original addition problem is:
2BA
+ C6D
8AD
Start by focusing on the units place (the rightmost digit) of the numbers. From the ones column, you can see that A + D = D.
Moving to the tens place, which is the column next to the right, we have B + 6 = A. Since B and A represent different digits, we cannot determine their actual sum at this point.
Now, let's move to the hundreds place. Here, we have A + C = 8. Since we already know A + D = D, we can conclude that C + D = 8 - D.
Since the sum of the two digits represented by B and C is required, we need to find the sum of B and C separately. Unfortunately, without additional information, we cannot determine their exact sum.
Therefore, the sum of the two digits represented by B and C is unknown.
To find the sum of the two digits represented by B and C in the given addition problem, we need to solve the equation:
2BA + C6D = 8AD
Here's how you can find the solution step by step:
1. Start by analyzing the rightmost column (the units column). The equation becomes:
A + D = D
Since A + D equals D, we can determine that A must be 0. This is because any number added to D will not change D as long as the units digit of that number is 0.
2. Now, let's move to the next column (the tens column). The equation becomes:
2B + 6 + C = 8
Rearranging the equation, we have:
2B + C = 8 - 6
2B + C = 2
To simplify things, we can list down all the possible values for B and C that satisfy the equation:
B = 1, C = 0
B = 0, C = 2
B = 3, C = -2 (not valid since we are dealing with digits)
Therefore, we have two possible solutions: B = 1 and C = 0 (or vice versa), and B = 0 and C = 2 (or vice versa).
Hence, the sum of the two digits represented by B and C could be either 1 + 0 = 1 or 0 + 2 = 2.
