How do calculators use logic gates to calculate?
In: Technology
You create logical circuits that do the operation you like.
In addition, you make a full adder and change as many as you need together for the calculation.
a full adder is added 3 bits, the carry from the previous adder, and one bit for each number. It output a result bit and a carry.
Carry is overflow from an operation
The operation is like you do when you add by hand on parer as you learned in school
35+26 can be split up. first adding 5 +7 to 12 so 2 out and 1 as a carry. Then you have 3+2 + 1( the carry from the precious operation= you get 6 out and 0 as a carry
The result is the output in reverse order so 2 and 6 is 62
If you do that with binary you can make the 3-bit addition with simple logic

Multiplication and division is harder buy you split than just like you did when you learn to do them in school
