# 1 plus 1 equals 2 why?

The explanation as to why 1+1=2 is complicated and I hope you understand it. It's mysterious, though, because first you have to come to a definition of what "1" means, what "2…" means, and even what "+" & "=" means! It's a lot harder than you think. The proof goes something like this (remember, it depends on set theory): We start off by defining the natural numbers (ie positive integers) in terms of sets. For any set S, define a "successor" function f as f(S) = {S, {S}} ie, the set containing: S and the set containing S. Then we define the natural integers as such: Define the number 0 to be the empty set, which I'll write here as O. Then each successive integer (ie "n+1") is just the preceding integer put through the successor function, ie 1 = {O, {O}} 2 = {O, {O, {O}}} 3 = {O, {O, {O, {O}}}} and so on. Then 1+1=f(1)={O, {O, {O}}}=2

# What is 1 third plus 2 fifths?

# What is negative 1 plus 2?

-1+2=1 If you have a negative number and a positive number subtract them. If the negative number is higher than the other number then it is negative. To change the expre…ssion but keep the answer the same you can do 2-1=1. Take out the addition sign and switch the numbers.

# What is 1 fourth plus 2 fifths?

The key to answering this question is to find your "lowest common denominator." (The denominator is the number below the line of the fraction.) If you multiply the denominator…s of the two fractions (4 and 5) you will come up with a common denominator (20). That will usually be your lowest common denominator. Then multiply each numerator (the number above the line of the fraction) by the denominator of the other fraction. The numerator of one-fourth is 1; the denominator of two-fifths is 5. Therefore, multiply 1 x 5 and you get 5. The numerator of two-fifths is 2; the denominator of one-fourth is 4. Therefore, multiply 2 x 4 and you get 8. Finally, add the results of your calculations: 5 + 8 = 13 Your new numerator is 13 and your new denominator is 20.

# What is 1 plus 2?

3. ________________ Having done extensive research, and contacting several consultants, I believe that 3 is the correct answer. However, it is fun to consider that w…e are making all kinds of assumptions. Yes, they are assumptions that are part of the standard arithmetic system. We are assuming that we really know what is meant by 1, 2 and 3, and we are also requiring that the "1" and the "2" be exclusive. Couldn't there be a system where exclusivity is indeterminate, or somehow has to be determined before an addition can take place? And what's addition all about, anyway?

# How do you explain 1 plus 1 equals 3 instead of 1 plus 1 equals 2 though it is correct?

It's about rounding numbers to their nearest whole number. Example, 1.3 gets rounded down to 1. Any number above x.5 is rounded up to the next whole number, so 1.5 or greater …gets rounded up to 2. Taking a mathematics example, 1.3 plus 1.3 equals 2.6. This rounded to the nearest whole number is 3.
