How it works
The first 2 bits represent A, the next 2 bits represent B, and the last 4 bits represent C.
Bit 1 = A1, Bit 2 = A0, Bit 3 = B1, Bit 4 = B0, Bit 5 = C3, Bit 6 = C2, Bit 7 = C1, Bit 8 = C0
A is multiplied by B and added to C. The output is shown on the 7 segment display, with the decimal representing "add 16".
How to test
- Set the switches to your desired numbers in binary
- For example A = 11b = 3d, B = 11b = 3d, C = 1111b = 15d
- The result will be shown on the 7 segment display
- For example 3 * 3 + 15 = 24 (showing an 8 and decimal adds 16 (8+16 = 24))
