 The formula for percent error is...
 OA/A * 100
 The A in the percent error formula stands for the
 accepted value
 The O in the percent error formula stands for the ...
 observed or measured value
 In physics, we hope for less than ... % error in the lab.

 13.0050 has how many sig digs?
 6  the zeros between 3 and 5 count because they are between nonzeros. The last zero counts ecause it is after a decimal AND ALSO after a nonzero.
 99.01 + 1 = ?

100.
99.01 goes to the hundreths place but 1 only goes to the ones place. Since you are adding, your answer must go to the ones place. Putting a decimal after the second zero makes both zeros count.  Write 1400 as scientific notation.
 1.4 x 10^3
