In math, an addend can be defined as the numbers or terms added together to form the sum. Here, the numbers 7 and 8 are addends. Here’s another example, in which the numbers 7, 4 and 9 are addends, and 20 is the sum.

There are 3 parts of addition, the addend, the equal sign, and the sum.

• The Addend. In addition, the addends or the summands are numbers or terms being added together.
• The Equal Sign. The equal sign indicates that the two halves of the equation are equivalent.
• The Sum.

Commutative property of addition: Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+44, plus, 2, equals, 2, plus, 4. Associative property of addition: Changing the grouping of addends does not change the sum.

The symbol used to indicate Addition is + (plus symbol). An addition sentence is a mathematical expression that shows two or more values added together and their sum. The numbers that are added are called addends and the answer to addition is called the sum.

How to Teach Addition | 7 Simple Steps

1. Introduce the concept using countable manipulatives. Using countable manipulatives (physical objects) will make addition concrete and much easier to understand.
2. Transition to visuals.
3. Use a number line.
4. Counting Up.
5. Finding the ten.
6. Word problems.
7. Memorize the math facts.

Maximum, In mathematics, a point at which a function’s value is greatest. If it is merely greater than any nearby point, it is a relative, or local, maximum.

The maximum value of a function is the place where a function reaches its highest point, or vertex, on a graph. If your quadratic equation has a negative a term, it will also have a maximum value.

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
