Yes. To determine the discount of 10%, move the decimal one space to the left. That will be the 10% discount. So if you're looking at a $100.00 item, the discount would be $10. If you're looking at a $79.85 item, the discount is $7.985 (or roughly $8.00).

Q: Can you calculate the amount of discount of a 100 item that is 10 percent off in your head and not perform any calculations on paper?

The two orders of operation are: Perform all calculations inside the parentheses first. Perform all multiplication and division starting from left to right.

With only a numeric keypad - none. You need at least some basic operations or functions such as addition, subtraction, multiplication and division.

Percent error is typically used to describe the difference between an expected value and an observed value (measured in an experiment). To calculate percent error, you must know the expected (or theoretical) value, determined from reference manuals and formulas. Percent error = [(actual measured value)/(expected value) - 1] x 100% Let's say that you do a chemistry experiment, where you expect to use 30 mL of a hydrochloric acid solution to neutralize a prepared solution of sodium hydroxide. When you perform the experiment, you actually use 30.2 mL of hydrochloric acid solution. Percent error = [(30.2 mL) / (30 mL) - 1] x 100% = 0.667 % error

The meaning of naturalistic is to take on the effects of nature or of naturally occurring. In math naturalistic means to use a teach method that promotes a natural way of thinking in a student so they can perform calculations based on real life experiences.
