Chapter 2: Math Operations 41 bound bound limits apply to the unknown variable value for which you are solving. Default bounds are {M1©99,1©99}. Use these limits to narrow the unknown value solution to a specific range of numbers, especially if more than one answer exists. Hint: For answers with many solutions (for example, trig functions), consider graphing the function first to get an idea of the most ideal (or specific) bound limits. Solve Specify the unknown variable from the Solve line. This prompts the calculator to solve for it. To select a variable on the Solve line, highlight the unknown variable with the cursor, and then press b. After you press b, a solid black square appears next to the solved (previously unknown) variable displayed in the Equation Variables section. Hint: The Solver allows for a small tolerance when solving a result, which is noticeable especially when solving complex equations or those with multiple solutions. For example, a result of 3.99999999999999 (instead of 4) for the equation 16=x2 is considered a correct answer. Solving Equations with Only One Possible Answer ³ For 2(L+M)=N, solve for L when N=268, and M=40, M14, and 307. 1. Define the equation on the EQUATION SOLVER screen. 16 $ : (if necessary)
