‫Welcome to the booth algorithm demonstration but the base story board for this demonstration we are
‫using the seven segments located on the basis three board to display your input one in your input 2.
‫We are also using two separate four digit seven segment displays on the breadboard to display the result
‫of this multiplication.
‫With bous algorithm we are working with Plaza's multiplication of signed numbers meaning we can do multiplication
‫of negative numbers or 2 positive numbers or one negative and one positive for the slides which is we're
‫using switch 0 which is a slack and determines whether we're displaying what 1 or input 2 on the 7 segment
‫display on the basis three board we're using switch one for add or subtract.
‫This determines when we are going to add or subtract in the values of input 1 and 2 the pushbuttons
‫we're using the push button right to be the add or subtract 1 push button down to add or subtract 10
‫and the push button left to add or subtract 100.
‫And then the center button is used to execute the command.
‫So to start out our select is called high meaning we're displaying or put one in or as contract as one
‫meaning we're adding.
‫So if I press one we're going to add one if I press 10.
‫We had 10 if I press 100 we had 100.
‫Now I can do a subtract by pulling the switch two down.
‫Now subtract 100 or subtract one.
‫So now my input 1 is a value of 10.
‫If I pull my switch zero down.
‫Now I'm displaying my input to which is the value of 0.
‫We can now to subtract.
‫And if we subtract 1 we'll see that instantly we get the notification that we have a negative number.
‫So we're at negative 1 and we keep going down we can keep subtracting sort negative 2.
‫So my input one by point slides which is ten point aside switch down the input 2 is a negative 2.
‫So 10 times negative 2 is negative 20.
‫If I press the center button we'll see that we now have a negative 20.
‫It shows up in the result register.
‫So we can do eight different combinations so we can do two negative numbers if I go back to my input
‫1 and we subtract subtract 10 and subtract 100.
‫So my input 1 is negative 100 my input 2 is a negative 2 which we know negative 100 times negative 2
‫is a positive 200 so we press her center button to execute and the result register now displays a 200.
‫And so we can go through any different combination of negative and positive numbers and to display them
‫on the four digit 7st display.
‫So we can go through and I'll just do a real quick.
‫We'll just make a large number negative for 33 and we'll make our second digit make it a positive positive
‫to 98.
‫So we have 298 times negative 4:33.
‫And if we multiply those.
‫The result is negative.
‫One hundred and twenty nine thousand thirty four.
‫And so a combination of negative and positive numbers up to negative nine hundred ninety nine through
‫nine hundred ninety nine.
‫We can get any different combination of those and display them with this demonstration.
‫Now does the demonstration boose algorithm running on the basis three board.
