Introduction: Essentials of elementary algebra:
Algebra is a branch of mathematics is use to construct the mathematical model of the real-world situations and to handle the problems that we could not solve the problems using the simple arithmetic. Using the words, algebra uses symbols to make statements.
Algebra includes real numbers, complex numbers, matrices, vectors etc. In algebra, we are frequently using the letters for represents the numbers in mathematics. Algebra is using the symbols as arithmetic operations for adding, subtracting, dividing and multiplying. I like to share this Distributive Property Definition with you all through my article.
Properties used in elementary algebra.
1. Commutative Property of Addition in algebra
The two numbers are adding any order (a, b or b, a), the sum value is the same.
a + b = b + a
2. Commutative Property of Multiplication in algebra
The two numbers are multiplying any order (a, b or b, a), the sum value is the same.
a * b = b * a
3. Associative Property of Addition in algebra
The associative property will take up three or more numbers. The parenthesis indicates the terms that are measured one unit. Hence, the numbers are 'associated' jointly. In multiplication, the product is at all times the same anyway of their grouping.
(a + b) + c = a + (b + c)
4. Associative Property of Multiplication
The associative property will take up three or more numbers. The parenthesis indicates the terms that are measured one unit. Hence, the numbers are 'associated' jointly. In addition, the sum is at all times the same anyway of their grouping.
(a * b) * c = a * (b * c)
Understanding Multiplying with Decimals is always challenging for me but thanks to all math help websites to help me out.
Example Algebraic Problem:
Example on elementary algebra:
-3(x + 7) = x + 7
Solution:
multiply factors in left term
-3x - 21 = x + 7
add 21 to both sides
-3x - 21 + 21 = x + 7 + 21
Group like terms
-3x = x + 28
subtract x to both sides
-3x - x = x + 28 -x
Group like terms
-4x = 28
multiply both sides by -1/4
x = -7
Check the solution
Left side:-3(-7 +7) = 0
right side:-7 + 7 = 0
Conclusion
x = -7 is the correct solution for the given algebraic equation.
