Put them one below the other so that the decimal points are aligned. Fill out to the right with extra zeroes, so that they have the same amount of decimals - or just imagine the missing zeroes.
Same rules as adding whole numbers with different signs.
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
1. When adding, the decimals MUST line up: 012.3 +32.1 2. When multiplying, you dont have to put the decimals side by side: 12.3 x323.55 Then you count how many numbers are after the decimals, which, in this case, is three. Hope it helped!
To add the two decimals together
keep your decimals in the right position
3rd. Adding Decimals 5th - Adding and subtracting 6th - Dividing Decimals

adding and subtracting protons from a gold atom would no longer make it gold.

line up the decimal point when your adding and subtracting. add annex a zero when you have extra number. sometimes you can use a number line.
There are several rules for decimals, depending on what you want to do.
I dont know
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
There is a system or strategy to adding them it is called DUD. Decimal Under Decimal 1.2 1.2+ 2.4 Now that's how you add decimals!!
