yes because ab plus bc is ac
The expression "A plus B equals AB" is not a standard mathematical equation. In traditional arithmetic, the plus sign (+) is used to indicate addition, where two or more numbers are combined to give a sum. However, in this case, it seems like the plus sign is being used as a concatenation operator, where the values of A and B are being combined as a single string of characters. Therefore, the statement "A plus B equals AB" would be interpreted as a string concatenation operation rather than a mathematical addition.
Ab = 25 CD
Difficult to tell when you cannot use parentheses. a*(b+c) or a(b+c) = ab + ac This is known as the distributive property of multiplication over addition.
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
