- Addition (+) and subtraction (-) round by the least number of decimals.
 - Multiplication (* or ×) and division (/ or ÷) round by the least number of significant figures.
 - Logarithm (log, ln) uses the input's number of significant figures as the result's number of decimals.
 - Antilogarithm (n^x.y) uses the power's number of decimals (mantissa) as the result's number of significant figures.
 - Exponentiation (n^x) only rounds by the significant figures in the base.
 - To count trailing zeros, add a decimal point at the end (e.g. 1000.) or use scientific notation (e.g. 1.000 × 10^3 or 1.000e3).
 - Zeros have all their digits counted as significant (e.g. 0 = 1, 0.00 = 3).
 - Rounds when required, after parentheses, and on the final step.

Answer: 68/67.8 toothpicks
Step-by-step explanation 
first convert how many inches 11.3 feet is
11.3 = 135.6 inches
so after you get your number you get your calculator and divide it by how many inches the toothpicks are
135.6 ÷ 2= 67.8
then to get a solid answer you would round it to a whole number
67.8--> 68
so you ether say the rounded number or you cut .2 inches off the last toothpick 
(also im not sure if its 11.3ft or 113ft so if so then take away the decimal and do the same math, you'll end up with 678 toothpicks)
