Best ResponseYou've already chosen the best response.1so I think you mean to say 2.5

Best ResponseYou've already chosen the best response.1the distance from 2.5 to 0 is 2.5 the distance from 0 to 1.5 is 1.5 the distance between 2.5 and 1.5 is the sum of the distances from 2.5 to 0 and 0 to 1.5

Best ResponseYou've already chosen the best response.0A = 2.5 B = 1.5  2.5  1.5 =  4 This number is also known as the opposite (number), sign change, and negation. so by using addictive inverse i am basically changing the 1.5 into 1,5 so,  1.5 +  2.5 =  4

Best ResponseYou've already chosen the best response.1anyways the distance from 2.5 to 0 can be found by doing 0(2.5) and the distance from 0 to 1.5 can be found by doing 1.50 and the distance from 2.5 to 1.5 can by found by adding those distances \[(1.50)+(0(2.5)) \\ (1.5)+((2.5)) \\ 1.5(2.5)\] we have written the subtraction expression they seeked

Best ResponseYou've already chosen the best response.1we can write it to an equivalent addition expression by using the fact that (2.5)=+2.5 so 1.5(2.5)=1.5+2.5
