What are Arithmetic operations?
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
Given that there are 3 walls
Each of the walls measures 12 feet by 10 feet.
One full wall has an area as :
⇒ (12)×(10)
⇒ 120 square feet
The total area of the three walls as :
⇒ (120)×(3)
⇒ 360 square feet
Hence, 360 square feet will she need to paint.
