Addition is the math operation of combining two or more numbers to get their total, called the sum. In French, addition is central to early math learning, helping students understand how quantities grow when joined together.
  • Operates on numbers (ingredients, objects, amounts) to find a combined total.
  • The two amounts combined are called addends (each number added).
  • The result is the sum (le total, la somme).
  • Used whenever things are combined—scorekeeping, shopping, measuring, etc.
  • A foundation for all higher-level math (+, -, ×, ÷).

Addends are the numbers being added.
The result of addition is called the sum.
Addition is used for combining or increasing quantities.

Basic Concept

Addition is about joining things together. If you have 2 apples and get 3 more, you add them to find out how many apples you have in total: 2 + 3 = 5.
  • Addition means putting numbers together to get a bigger number.
  • Numbers you add are called addends.
  • The answer you get is called the sum.
  • The plus sign (+) shows you are adding.
Addition combines numbers or quantities.
Addends are the numbers you add.
The result of addition is called the sum.

Numbers Used

You use any numbers you want to add—whole numbers (integers), fractions, decimals, or even negative numbers. But for early learning, it's usually positive whole numbers.
  • Commonly add whole numbers (0, 1, 2, 3, ...).
  • You can also add fractions (1/2 + 1/3), decimals (2.5 + 3.1), and negative numbers (-2 + 3).
  • Early math focuses on positive whole numbers.
Early math uses whole numbers for addition.
You can add whole numbers, fractions, decimals, and negatives.
No, you can add many kinds of numbers, but basics focus on whole numbers.

Symbols and Terms

Addition uses simple symbols:
  • + means add.
  • = means equals.
  • Terms: addends (numbers you add), sum (result).
SymbolMeaningExample
+Addition2 + 3 (add 2 and 3)
=Equals2 + 3 = 5 (is 5)
'+' means add.
'=' means equals.
Addends and sum are used in addition.

Example: Simple Numbers

If you have 4 toy cars and get 5 more, how many do you have total?
4 + 5 = 9
Addends: 4 and 5
Sum: 9
4 and 5 are the addends.
The sum of 4 and 5 is 9.
You're performing addition.
4 and 5 are the numbers being combined.

Example: Everyday Use

You buy 3 apples and 7 oranges. How many fruits do you have?
3 + 7 = 10 fruits
  • Combine items to get a total.
  • Used in shopping, cooking, packing, etc.
Addition is used to combine quantities.
The sum of 3 and 7 is 10.
3 + 7 = 10 represents the total fruit.

Example: Multi-Digit

Add 47 and 36.
47
+36
----
83
  • Align digits by place value.
  • Add tens and ones separately (sometimes carry over).
You align digits and add each place value.
47 + 36 equals 83.

Conclusion

Addition is about bringing numbers together to find a total.
  • Addends are the numbers added; the sum is the result.
  • Use + for addition and = for equals.
  • Addition applies to many everyday situations.
