Algebra is a method to simplify calculation, a method to reunite broken parts, a method to solve puzzles. Algebra skills are very important for an electronic engineer (or maybe for hackers) to solve any circuit problems related to mathematic. Not too much words, below is example of algebra problems and the problem solver:

**Algebra Problem 1. simplify :**

4a + 3b² – a + 2 = 38

**Problem Solving:**

4a + 3b² – a + 2 = 38

(4a – a) + 3b² = 38 – 2

3a + 3b² = 36

√3a + 3b = 6

**Algebra Problem 2, find y :**

5y+50 = 2 (3y + 10 )

**Problem solving:**

5y+50 = 2 (3y + 10 )

5y+50 = 6y + 20

5y +50 – 20 = 6y

5y + 30 = 6y

30 = 6y – 5y

y = 30

**Example problem 3, find value of i:**

2 = i + √3

**Problem Solving:**

2² = i² + 3

4 = i² + 3

i = 1

**Example problem 4:**

Simplify: 2x + 3(x + 10) = 55

**Problem Solving**

2x + 3x + 30 = 55

5x = (55-30)

5x = 25

x = 5
