Seeing that a large number and a decimal number make up ten addends is to look at the big addend, decompose the small addend, so that part of the decomposed addend and the big addend add up to 10, and then add up the rest.

In mathematics, the larger of two numbers. Represents the 72nd power of 10. In programming, large numbers represent numbers over 32 bits. Decimal is a special expression of real numbers.
