Answer 1

Answer:

Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division).

Examples- (2x+ 4x)

2(4z+2z)

X(3+4)

5x(6y+6z)

2h(5z+z)

Answer 2

.

Algebra is the branch of mathematics that uses letters in place of some unknown numbers.

You've been using algebra since your early schooling, when you learned formulas like the area of a rectangle, with width w, height h:

A = w × h

We used letters to stand for numbers. Once we knew the width and height, we could substitute them into the formula and find our area.

Another one you may have seen is the area of a circle, with radius r:

A = πr2

As soon as we know the length of the sides, we can find the area.

Literal numbers (the letters used in algebra) can either stand for variables (the value of the letter can change, like the w, h and r in the examples of the area of a rectangle and the area of a circle) or constants (where the value does not change), for example:

π (the ratio circumference/diameter of a circle, value 3.141592....)

g (the accelaration due to gravity, 9.8 m/s2),

e (which has a constant value of 2.781828...).

And as my students constantly ask..
