Neil does not make a mistake during calculation of expression.
What is expression?
Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?
Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from 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 the expression as :
⇒ 5⁻⁶/5⁻⁴
⇒ 5⁻⁶⁻⁽⁻⁴⁾
⇒ 5⁻⁶⁺⁴
⇒ 5⁻²
⇒ 1/5²
Hence, Neil does not make a mistake during calculation of expression.
