Which equation is wrong? A) Two plus four is equal to six minus one, B) six minus two is equal to three plus one, C) five plus one is equal to zero plus six, D) two plus three is equal to four plus one, or E) one plus three is equal to eight minus four.

In order to know which equation is wrong or incorrect, we need to go through and simplify every single equation. So let’s begin with A. Is two plus four equal to six minus one? Well, two plus four is equal to six, and six minus one is equal to five. Is six equal to five? No. So equation A is wrong.

Now let’s go ahead and go through all of the other ones just to be safe. For B, we have six minus two is equal to three plus one. Well, six minus two is equal to four, and three plus one is also equal to four. So four is indeed equal to four, so this is correct.

Now let’s look at C. Is five plus one equal to zero plus six? Well, five plus one is equal to six, and zero plus six is also equal to six. So C is correct.

For equation D, we have two plus three is equal to four plus one. And two plus three is equal to five, and four plus one is also equal to five. So this is correct.

Now, lastly, let’s look at E. It should be correct because we think we’ve already found the wrong one, A. So we have that one plus three is equal to eight minus four. Well, one plus three is equal to four, and eight minus four is equal to four. So this is also correct. So the equation that is wrong must be A.
