Three To write it out and work the problem: 2 + 1 = 3
Or, for a visual demonstration: Lay two coins on the desk in front you. Get one more coin from somewhere else and lay it (ie., add it) next to the other coins already on the desk. There will now be a total of three coins.
no if 1 plus 1 equals 2 then 2 plus 2 equals 4.
4
1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5
One plus one is two. It can be expressed mathematically as 1+1 = 2.
It equals 7
1/2 + 1/2 + 1/2 + 1/2 = 2 2 is four halves.
1+1 or 1 plus 1 is equal to 2.
30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
2 9 1 plus 1 is 2.
To find the mean (or average) you first add up the numbers you have. NOTHING 1.88
It equals 6
1/2 plus 1/6 = 2/3
