How you can prevent overflow in arithmetic?
Because integer overflows occur only for specific operand values in otherwise valid code, the only reliable way to prevent them is to use overflow checks or value sanity testing for every integer operation where an overflowing value could theoretically appear.
What is the use of arithmetic operations in programming?
An arithmetic operator is a mathematical function that takes two operands and performs a calculation on them. They are used in common arithmetic and most computer languages contain a set of such operators that can be used within equations to perform a number of types of sequential calculation.
Who invented addition and subtraction?

How do you do multiplication in math?
In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The two factors and the product are parts of a multiplication problem. In the multiplication problem, 6 × 9 = 54, the numbers 6 and 9 are the factors, while the number 54 is the product.
What is overflow and underflow of data in C?
The situation where an integer outside the allowed range requires more bits than can be stored is called an overflow. Similarly, with real numbers, an exponent that is too small to be stored causes an underflow.

What are the numbers called when we apply multiplication operation in them?
It is necessary to know, what are the numbers called when we apply multiplication operation in them. The multiplicand is the number which is being multiplied The multiplier is the number which is multiplying the first number. For example: In this operation, 45 × 20, 45 is the multiplicand and 20 is the multiplier.
