how can I prove that 1+1=2???

Answer 1

take one thing and another thing, put them together and you have two things

Answer 2

2-1=1

Answer 3

you are on 1. when you are adding, you are going up. if you are adding 1 to 1, you are going to go up 1. so you stop at 2. so that is how you prove 1+1=2

Answer 4

You must start by defining 1 as unity. Which means that the symbol 1 denotes a single unit.

Next define 2 as denoting 2 units

next define the + as an operator that combines the symbols into the sum of the parts.

Next, define = as denoting the outcome of an operation.

then 1 + 1 =2

j

Answer 5

1+1=2 (minus 1 from both sides)
1=2-1
1=1 (minus 1 from both sides, again)
0=0

Answer 6

LOGICALLY:
u have one cow in ur farm....if u buy another cow and put it in ur farm....by counting, u can conclude that u have 2 cows

MATHEMATICALLY:
1. (1+1)=2
2-(1+1)=0
2-2=0
0=0 TRUE
2. let x=1
x+x=2
2x=2
x=2/2
x=1 TRUE

this is a really dumb question.

Answer 7

duh!!

1+1 = 2
2 -1 = 1

Answer 8

You could use a number line from 0 to 10 where zero is starting point and each mark on it represents one unit. From zero right Count two units.

Answer 9

Get one bean and another one bean, put them side by side and now you have 2 beans. You can use this with any number to prove the results.

Answer 10

if you do 2-1... (the reverse) it equals 1.

so therefore, you've proven that the equation works both ways!

Answer 11

WOW! Thats a tough one,try adding
