Using Calculator 59
Reusing the last answer
Each instance of Calculator automatically stores the last calculated result
as a variable named Ans. You can use Ans to create a chain of
calculations.
Note: Do not link to Ans or any system variable. Doing so could prevent
the variable from being updated by the system. System variables include
statistics results (such as Stat.RegEqn, Stat.dfError, and Stat.Resid) and
Finance Solver variables (such as tvm.n, tvm.pmt, and tvm.fv).
As an example of using Ans, calculate the area of a garden plot that is 1.7
meters by 4.2 meters. Then use the area to calculate the yield per square
meter if the plot produces a total of 147 tomatoes.
1. On the Calculator entry line, type
1.7*4.2, and press Enter.
2. Type
147/ans, and press Enter to find the yield.
As a second example, calculate and then add
2*log(45).
3. Type
3.76/(-7.9+sqrt(5)), and press Enter.
4. Type
ans+2*log(45), and press Enter.
