Prove that (1+1=1)?

Answer 1

The AND Logic Gate

1 (AND) 1 = 1

Answer 2

Nur S is almost right, yet I think she is an electrical ( or electronical ) engineering student I guess. That must be the reason, she referred to AND logic gates.

Logic gates are based on the two-valued Boolen algebra ( switching algebra ) represents the properties of bistable electrical switching circuits.

However, as this is a mathematical question, you should use an algebra system, yet it cannot be resolved with the help of simply algebra. Therefore, you can solve it by using the two-valued Boolen algebra.

AND function defined in the two-valued Boolen algebra :

a b z=a.b
0 0 0
0 1 0
1 0 0
1 1 1

Edit : james w is right too. It may be an OR function :

a b z=a+b
0 0 0
0 1 1
1 0 1
1 1 1

Answer 3

1= 0,5
1+1=1

Answer 4

if u place a zero 0 ( 1 + 1 = 1 )

Answer 5

1 = 1
1 = √1
1 = √[-1*-1]
1 = -1
1+1 = 1-1
1+1 = 0

oops

Answer 6

That occurs in combinational logic circuits. 1+1=1 is an OR gate. It goes high when ANY output is high. The only time it is 0 is when 0 + 0 exists.

Answer 7

It doesn't exist, but here's how the proof would look like if it did exist.
"Proof" that 1 + 1 = 1

a = 1
b = 1

a = b
a2 = b2
a2 - b2 = 0
(a-b)(a+b) = 0
(a-b)(a+b)/(a-b) = 0/(a-b)
1(a+b) = 0
(a+b) = 0
1 + 1 = 0
2 = 0
1 = 0 (Divide both sides by 2)
1 + 1 = 1 (Add 1 to each side)

Answer 8

try prove yourself why (1+1=2) first

Answer 9

If 1 =x
x+x=1
2x=1
--- ---
2 2

x=.5
.5+.5=1

Therefore, 1+1=1

Answer 10

Since one is it's individual self. You cannot add it to itself, therefor 1+1=1
