Hello! I have a project for my school about addition. I completed this circuit with the required components but it doesn't seem to work. can you help me figure out what is wrong?

Hello Nicksama,

Can you elaborate on why it doesn´t seem to work? do you get errors? Is nothing happening? unexpected results? What should the circuit do?

You can as well attached your schematic so other users can see what components you are using and what is going on.

Hello and thanks for replying!

Well for starters, i get nothing when i simulate it. no errors, just nothing.

It is supposed to insert 2 numbers and just add them and see the results on the 7-segment display. That's all i want it to do. all the components were suggested by my professor.

Thank you.

Hello Nicksama,

If you are having some trouble with the way to configure 7 segments, you can review the examples that ship with Multisim like the Sync BCD Counter to have a better understanding and then applying it to your design.
