When do you subtract

• Neither are correct

• You do this with exponents when performing simple equations for chemistry

• You do this with exponents when lessening the exponet

• You do this with exponents when performing metric conversions

What does the difference tell you?

• It tells you how many places to go back the decimal and in which placement it is

• It tells you how many places to move the decimal and in which direction

• It tells you how many decimals are there

• It tells you difference between Table C and Table D

What is the smaller value?

• When going from a smaller equation to a bigger equation (9--6 --> 9+10--6+3)

• When going from a smaller number to a bigger number (1 --> 2)

• When going from a smaller unit to a bigger unit (g --> kg)

• When going from a bigger unit to a smaller unit (kg --> g)

What is the bigger value?

• When going from a larger exponent to a smaller unit (10^0 --> 10^5)

• When going from a larger millimeter to a smaller centimeter (km --> cm)

• When going from a larger unit to a smaller unit (km --> cm)

• When going from a updrage to a downgrade

What are sig fig's

• Signed fig's

• Somewhat includes all known digits and one that is estimated

• Disincludes all known digits and one that is estimated

• Includes all known digits and one that is estimated

What do you do to determine something between a whole number to another whole number?

• You use 1/10ths decimals. (Ex 16.2 13.4 27.6 or 99.8)

• You use 1/100ths decimals. (Ex 16.21 13.44 27.68 or 99.89)

• You use 1/5th decimals. (Ex 16.5 13.5 27.0 or 99.0)
