In the expression "3 + 4 = 7", what are 3 and 4 classified as?

In the expression "3 + 4 = 7," the numbers 3 and 4 serve as operands. Operands are the entities that operators act upon in a mathematical expression. In this case, the operator is the addition symbol (+), which performs an operation on the two operands, 3 and 4.

Operands can be numbers, variables, or more complex values that are used in calculations. Here, 3 and 4 are simple numerical values that directly participate in the addition operation to yield the result, which is 7. This understanding is crucial as it differentiates between the roles of numbers within expressions—where operands are the subjects of the calculation, and operators are the symbols that denote the operation to be performed.
