16 Bit calculator that should be able to do most problems comprising of addition, subtraction, multiplication, and division through coding it

Cant do negatives or decimals

Can be programmed to do a variety of things, and can output to either numerical display, or a graphical display(yes you can graph functions to an extent)

Old project from awhile ago that I stopped working on due to lack of ideas

Add numbers from zero to three at the top (input 1) and bottom (input 2) and see what you get on the other end.

working on a (bad) calculator.

A simple 8-bit full adder / substractor.

S will compute the result of A + B or A - B

Use 7 bit numbers in subtraction mode (at least for B, to prevent an overflow).

Based on TD4, a 4 bit CPU.

Pre-design for Minecraft.

A simple binary calculator.

The possible instructions are:

• 0 ADD12
• 1 SUB34
• 2 INC56
• 3 DEC78
• 4 NOR90
• 5 AND12
• 6 XOR12
• 7 LDV12
• 8 LDR12
• 9 STR12
• 10 BRZ12
• 11 NOPXX
• 13 LBL (future)
• 14 future (probably something display-related)
• 15 future (probably something display-related)

It is possible to program by writing directly to the keyboard or by loading into program memory, to write to program memory you need to make an assembler first.

Soon I will host this assembler on a website.Subcircuits that I need help with:

• 8-bit registers (with the option to increment, get value, and save a value).

• ULA parts of the above instructions

• Ideas for graphical circuits

• Or other ideas

Intento crear una especie de calculadora a ver si soy capaz

Just an 4bit calculator made for fun and learning. Used the Alu in 4bit and made a 4bit Reg to safe numbers that the alu can calculate.

This is a 4 bit adder.

Only addition works right now, i am working on multiplication next

I am on a journey to make a full calculator. This is the start of my journey and im bringing you along with me. Look at the How it Works tap to learn with me and look at the adder tab to see the 4 bit adder!

binary calculators

the titles are the range of numbers you can add together

A simple 16-bit calculator that can add and subtract two numbers together.

i have made this mini calculator 

8-bit Calculator

Description:
This project Can do 4 different operations on a number Add, subtract, Multiply, and Divide.

How to Use:
Type in the keyboard, to type numbers, and note if you go over 255 it might break (click clear to fix).

Click the button for an operation. Note: Click on the same operation again to remove it. This will be useful when changing operations because if you do not do so it will think that it needs to do 2 operations at the same time.

Click the button that says selected data to choose from the top or bottom when typing in the numbers.

How it Works:

Inputs are converted to BCD and Binary. the binary is then put into all of the operations(Add, Subtract, Multiply, Divide)

ADD: Use a ripple carry adder.

Subtracter: Adder with an Invert B and a Carry-In.  if Carry Out on then it is a positive number and if off it is a negative. If negative it will then invert again and add on, to get the negative result.

Multiplier: I have no idea how this one works.

Divider: Same here(I did have to double the input size thought)

The outputs of all these operations into a multiplexer which chooses what input will go into the display.

Display: HEX display

Answer: convert binary to BCD(very hard) I made it but I did use help by watching a tutorial.

Note: I only used the logic from 0:52 to 3:00
