Evaluate
2 • 32 - 1 =

If you follow the steps of PEMDAS, exponent comes first so

3^2=9

So your equation will be

2*9-1=?

Then multiply

18-1=?

17 is the answer.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
