What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Total tuition fees;

6 × 530 = $3180

Books cost = $1800

Total cost to get a degree = Total tuition fees + Books cost

Total cost to get a degree = 3180 + 1800 = $4980.

Hence "The total cost for Neil to get his degree is $4980".

Explain when is a rational expression restricted.

Answers

basically, domain is all real numbers that cause an not allowed
some things that aren't allowed are dividing by zero and taking the square root of a number less than zero, restrict all values that make thos things hapen

exapmle

a/b, b can not be zero

(3+x)/(4-x)
x cannot be 4 since that would be dividing by zero

another example
√(x-3)
x cannot be less than 3 because that would make a sqrt of a negative

basiccally restrictions are not allowed becasue we don't understnad what happens when we break them
