Do the division, it will be displayed in fraction form.
Then press "Shift S--D" to transform the result in mixed fraction form.
The modulus is the nominator of the fraction.

Example: We need 73 mod 7, we input 73/7= , then we press "Shift S--D" and we get mixed fraction: 10 3/7
3 is the result of 73 mod 7
(and 10 is the result of 73 div 7)

Addition: Just make sure you have a denominator equal to 7 (or to required operand). If not just calculate the required. ex 28/6 = 14/3 = 4 2/3

So 28 mod 6 will yield 4 because 28/6 = 4 4/6

SOURCE: HOW CAN I INSERT THE

Sorry, but you cannot.
You can type in a formula that involves the memory variables X,Y, A, B,C,D, E, =, . Such a formula is meant to be evaluated to get a solution (X by default). Once you type the formula you press the Shifted function SOLVE and you will be prompted for the constants, for Y etc. when you press the EXE/= key you get the value of X.
If you turn off the calculator or change the calculation MODE, it is wiped out of memory.

To make a long story short, you cannot STORE formulas in the calculator. Better try to memorize them (commit then to YOUR OWN memory).

It's a bit convoluted, and it only works for integers, but here's one way. Press MODE 4 to switch to BASE-N (integer) mode. If the screen doesn't read "Dec" then press the x^2 key. Now, to calculate a mod b, calculate a-a/b*b. No shortcuts, no rearranging. That's a minus a divided by b times b. You have to enter both numbers twice, but you will get the modulus.

There isn't a problem per se. The calculator is simply showing you the result as an improper fraction.

Press the S--D key to toggle the result between symbolic and decimal forms. To have the results always come up in decimal, press SHIFT [SETUP] 2 to select the LineIO mode.

### How to change a decimal value to binary number in fx-85GT PLUS ? Thanks!!

Let's do the preocess so it will work on any calculator.

As an example, convert 68 from decimal to binary.

The decimal columns are 10^0, 10^1, 10^2, 10^3, etc.

The binary columns are 2^0, 2^1, 2^2, 2^3, etc.

Flipping to the normal left to right, we get 2^6, 2^5, 2^4, 2^3, 2^2, 2^1, 2^0.

64 32 16 8 4 2 1

We divide our number, 68, by 64, and get 1 with a remainder of 4. We next divide our remainder by 32, 16, 8, and finally 4, where we get 1 with no reminder.

In binary, this works out to 1000100. To check, we multiply the ones by the respective column values and get 64 + 4 = 68.

Good luck.

### Please ca you show me how calculate the tenth root of 1.797 on a casio fx-85GT plus

If you have the so-called xRoot key you procede as follows; 10[xRoot] 1.797
If you do not have an xRoot key you use the equivalence nth root of x= x to the power of 1/n
In the case of the 10th root you type (1.797)^(1/10) or (1.797)^(0.1). Here the [^] caret is the general power key. On some calculators it is marked as [X^y] or [Y^x]
