To solve equations on a TI-Nspire CX, use the solve() function by pressing Menu > Algebra > Solve, then type your equation, a comma, and the variable (e.g., x^2-4=0,x), or use the nSolve() for numerical solutions (Menu > Algebra > Numerical Solve) for complex equations, often adding bounds like nSolve(equation, variable, lower_bound, upper_bound) for specific answers or systems of equations via the template.
To display as exact values, please see the following example:
You can write "I love you" in a calculator by typing numbers that look like letters when flipped upside down, like 710734 (spells hELLO) or using the number sequence 143, which means "I love you" (one, four, three letters). For a visual trick, type 371073 and flip it, or use 17734 for "hello".
Solving for some equations on TI-89 family, Voyage 200, or TI-Nspire Family CAS handheld (includes: TI-Nspire CAS with ClickPad or TouchPad and TI-Nspire CX CAS) will sometimes return an answer of "false." This is caused by the equation having a non-real solution.
Choose Solve( from the Algebra menu (or just type it); enter the equation , followed by ',x' and press ¸. CAS calculators can be used to solve linear equations.
Typing 5318008 into a calculator and turning it upside down spells "BOOBIES", a classic example of calculator spelling or "beghilos" (letters from numbers), where 8=B, 0=O, 1=I, 3=E, and 5=S, creating a childish but nostalgic word.
Customers are saying. Customers find value in the TI-Nspire CX II Handheld Graphing Calculator's ease of use, its affordability, and the numerous features it offers.
Bee = type 338 and flip your calculator upside down. Eggs = Type 5663 and flip your calculator upside down.
If your display is big enough, you can enter 53177187714, which makes hillbillies; mine has only ten digits so I get illbillies (sick goats?) and the longest word I can make is 378193771 (appropriately, illegible). The trick is known from other countries; for example in German 38317 spells Liebe.
In media. On Mister Rogers' Neighborhood: "Transformations", 143 is used to mean "I love you". 1 meaning I for 1 letter, 4 meaning Love for the 4 letters, and 3 meaning You for the 3 letters.

Bring the variable terms to one side of the equation and the constant terms to the other side using the addition and subtraction properties of equality. Make the coefficient of the variable as 1, using the multiplication or division properties of equality. isolate the variable and get the solution.
