## equals sign

In programming, the equals sign (=) is used for equality and copying. For example, if x = 0 means "if X is equal to zero;" however x = 0 means "copy the value zero into the variable X." Double equals signs (==) means equals to in C. For example, if (x == 0) means if X is equal to zero. The unusual use of the double equals sign causes many errors in C programming.

CAL intervention was divided into six units: (a) equal sign as a relational term, (b) addition concepts and operational strategies for problems for which retrieval is a viable strategy (problems where both operands are one digit or one operand is one digit and the other is two digits but regrouping is not required), (c) concepts and operational strategies for similar problems involving subtraction, (d) concepts and operational strategies for addition problems with regrouping, (e) concepts and operational strategies for subtraction problems with regrouping, and (f) review (although cumulative review was also integrated throughout the first five units).
