The least common multiple of 3 and 4 is 12, so the particle x of candy is a multiple of 12;

That is, x = 12k(k is an integer)

The other 40

So k = 4

So x = 48.

The relationship between data and operators

1) natural data representation. For example, find the area of a curved trapezoid;

2) Manual data processing (such as data in the program;

3) Manual processing of natural data. For example, a part of an image is enlarged.

In mathematical formulas, data and operators have specific and detailed relationships, such as data number, left and right functions, formula form and so on.
