As you know, to figure out the "answer" using Significant figures, the rules are different for add/subtract than multiple/divide. 
 
*For Add/subtract, it is about the LEAST number of Decimal places of the number that you add/subtract together.
Ex: 
 
*For multiple/divide, it is the number(s) found in the problem with the "least number of Sig Figs. 
Ex: 
 
*Rounding to correct answer (either # of Sig fig or decimal places): 
**For multiply/divide: count left to right on number to get one (1) more sig fig digit 
or 
**For add/subtract: Go to lowest decimal place and go one (1) column to right. 
**Then if number is a) 5 or above, add one to column to left or b) less than 5, do nothing to column to left. 
 
Ex: 
 
------ 
Try on your own: 
 
1) (3.40m)(40.10m) = ____________________ = ________________ 
*Type of math: ___________ Looking for: Decimal place or # of sig fig (Circle one) 
*Where to round:
**Put horizontal line after final column/digit:
**Look at digit to right and round the digit to the left of the line (show number with horizontal line) 
**Give correct number after rounding on second line. 
 
2) 3.2m + 4.050m + 12.m = ______________ = _________________ 
 
*Type of math: ___________ Looking for: Decimal place or # of sig fig (Circle one) 
*Where to round:
**Put horizontal line after final column/digit:
**Look at digit to right and round the digit to the left of the line (show number with horizontal line) 
**Give correct number after rounding on second line.
