2.61 You just have to line up all your decimals and then add down: 2.000 0.600 0.010 +_____ = 2.61
plus sign (+), minus (-), number (#), decimal point for decimals and money, percent (%), dollar sign ($), equal (=)
Addition in decimals is commutative; that is, it doesn't matter what order you add the numbers, they will give the same result. So 3 + 6 = 6 + 3 = 9.
Yes. Do it like regular addition, only with decimals.
It depends what base you are in. We almost always use base 10, but in base 3, 1 plus 1 could equal 3. * * * * * Not true. The base 3 equivalents of the first few decimals is: 010 = 03 110 = 13 210 = 23 310 = 103 410 = 113 So 1 +1 is still not three and it will not become so simply by changing the base. 1 plus 1 can equal 3 if you redefine the operation "plus".

what does seven plus equal
2 plus 2 equal 4
11/28 To add two fractions, you need to make the bottoms of both the same. One fourth is equal to 7/28, and 1/7 is equal to 4/28, so added they equal 11/28. You could also ind the answer by converting both to decimals, and adding.
8.00 plus 7.40 plus 68 is equal to 83.4.
