2
Q
Define “Exponentiation”
A
- Raising a number to a power
3
Q
Define “Operation”
A
- A mathematical process
4
Q
Define “Order of Operations”
A
- A set of rules that explain in what order operations should be completed in an expression with more than 1 operation
5
Q
What is the 1st fact of exponentiation?
A
- a1 = a for any number a
6
Q
What is the 2nd fact of exponentiation?

7
Q
What is the order of operations?
A
- Parenthesis
- Exponents
- Multiplication (left to right)

8
Q
What is the most common mistake when solving multi-operation expressions?
A
- Not following the order of operations
9
Q
What is the 2nd most common mistake when solving multi-operational operation expressions?
A
- Trying to use a calculator to solve the expression. Most calculators don’t follow the order of operations
10
Q
What is the most common mistake when solving exponential operations?
A
- Multiplying the number by the exponent instead of the number by itself
