Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Let Thomas's age: x
∴ Grandfather's age: 100
As per the questions
Thomas is grandfather's 100 years old.
Thomas grandfather is 10 times as old as Thomas.
Grandfather's age = Thomas age
100 = 10x
10x = 100
x = 100/10
x = 10
So, Thomas's age is 10 years
