Enter the very first number then push the "+", "-", "x" or "/" (division), depending upon the operation. Go into the following number and then the "=" to finish the operation. Since the TI-30Xa performs mathematical work in the order of parenthesis, exponents, multiplication/division and also addition/subtraction, you have the right to enter whole expression v multiple operations at once.
Enter the number then push the "+/-" button to readjust the sign of the number from optimistic to negative. The "+/-" switch is actually pictured together a "+" and also "-" v two arrows producing a circle in between them.
Enter a "(" before entering an operation collection - definition a collection of numbers and also the operation(s) gift performed - and also a ")" after ~ the operation collection to indicate that the calculator have to perform the fastened operation(s) before performing any type of operations that follow. Again, this complies with the order of operations.
Enter the basic number, then the "x^2" (x-squared) button to square the number entered. Because that a cubed number, enter the basic number, then "2nd" and also "x^3" (x-cubed).
Enter the base number, climate "y^x" (y-to-the-x-power) and the exponent number for any exponent other than 2 or 3.
Enter the number within a radical (the square source symbol) and also then the square root button. The square root switch shows the square root of x. The cubed root of a number is uncovered by start the number within the radical, then "2nd" and the cubed source button. The cubed root button looks prefer a square root symbol with a 3 ~ above the outside and also an x inside.
Enter the number within the radical, then "2nd" and the x-root button for any type of root other than the square (2) or cube (3). The x-root switch looks like a square root symbol v an x ~ above the outside and a y top top the inside.
Enter the number and also then "LN" for the natural log that a number. The TI-30Xa does not permit for logarithms through bases other than 10 or the herbal number e.
