Explanation

The additive identity of a real number is zero (0).

This means that when you add zero to any real number, the result is the original number itself.

For example, 5 + 0 = 5, and -3 + 0 = -3. 

Explanation

The array {1 2 8 3} has 1 row and 4 columns.

So, its order is 1 × 4.

Explanation

y = mx + c

This is called the slope-intercept form, where:

 m = slope of the line

 c = y-intercept (value of y when x = 0)

It shows how y changes with x in a straight line.

Explanation

 25 million = 25,000,000 → There are 6 zeros.

Explanation

4 × 5 + 3 = 23.

First, multiply 4 by 5 to get 20, then add 3 to get 23.

Explanation

The coefficient of -2x is -2

Explanation

• A cyclic group is a group that can be generated by a single element, i.e., every element in the group can be expressed as a power of that element.
• Cyclic groups are always Abelian, meaning that the group operation is commutative (i.e., the order of elements does not matter).
