“Addition” is a very common word in modern English, usually learned at around the A2 level.

They are opposite arithmetic operations. Addition combines numbers to find their total, or sum — 3 plus 4 makes 7. Subtraction takes one number away from another to find the difference — 7 minus 4 leaves 3. Addition builds a larger total; subtraction reduces one. Each undoes the other.

Adding 2 and 5 to get 7 is a simple example, written 2 + 5 = 7. The numbers being added are called addends, and the result is the sum. Everyday addition includes totalling a shopping bill or combining scores — any time separate amounts are joined into one total.

In an addition problem, the numbers being combined are called addends, and the answer is called the sum or total. The plus sign (+) shows the operation, and the equals sign (=) introduces the result. So in 6 + 3 = 9, six and three are addends and nine is the sum.
