Instructions and Help about Which Form 8815 Calculator

Hi everyone I'd like to present my latest model which is a simple lego technic calculator it can perform addition subtraction and calculate the average of two numbers on the Left we have two sliders that I can move back and forward and their values are represented by the red liftarms for example I have the number 2 plus the number 4 equals the number 6 the average of 2 and 4 is represented by the yellow lifter in this case it's the value 3 I can lock the number 6 in place and move the sliders and at all times these will add up to the value of 6 so we have 2 plus 4 3 plus 3 4 plus 2 we also have the values in between so we can do 3 point 5 plus 2 point 5 equals the value 6 if I want to do subtraction I can set the value that I want in the middle to say 5 minus 4 equals 1 I can also lock that value in place and I can move them the sliders so we can see all the values so we can say 5 minus 3 equals 2 5 minus 2 equals 3 5 minus 1 equals 4 if you have any questions please leave them in the comments and thank you for watching.
