• Where are exponents in the order of operations?
• Sorry, I realize I´m 2 years late.
But for those who need help, there are two ways of remembering the order of operations:

Excuse (Exponents)
My (Multiplication)
Dear (Division)
Sally (Subtraction)

or

Pour (Parentheses)
Everyone (Exponents)
My (Multiplication)
Delicious (Division)
Sauce (Subtraction)

Use whichever is better for you! Hope this helped!
• Why can't you just do 10 x 6 instead of doing 10 x 10 x 10 x 10 x 10 x 10...?
• 10 x 6 = 60, while
10 x 10 x 10 x 10 x 10 x 10 = 1,000,000
They both give very different answers.
• What is 15.023 multiple by 10-2
• that would be 1502.3
• so if you 10x10x10=1000 and like 10x10x10x10x10=1000,000
• I'm not sure what you're trying to say, but 10x10x10x10x10 is actually 100,000.

Hope this helps, pls let me know if it doesn't.
Also, sorry for being 4 years late.
