Question

I simply just do not understand this it is confusing and it is my last question so if you could help me that would be really awesome.

Answer 1

a=5

b=9

c=3

d=4

Step-by-step explanation:

Answer 2

A=5, B=9, C=3, D=4

Step-by-step explanation:

For example 3+1 = 4 and it also shows that D = 1+3. It could get confusing if you try and connect the columns with rows and make a double digit sum when you should only focus on one column or row and not mix them up making the wrong result. For example starting from the number 2 in the top row (3+2=A) and add number 1 to the is where one could mess up the puzzle when it should be 3+2 = A only. And that’s how it’s done. Good luck!
