Elementary math covers all the basic operations, function and concepts in algebra. In elementary math is the main part covered is arithmetic operations. All the basic operations are presented in this area. This is covering all basic operation of addition multiplication, subtraction, and division. The elementary algebra covers all concepts from kindergarten level to middle school level. This is also help to solve for real life math problem.
Example: 4x+ 2 = 1
Elementary Math Concepts Covers:
Elementary math concepts contain this basic operations
Arithmetic Operations:
The real numbers have the following properties:
a + b= b + a ab = ba (Commutative Law)
(a+ b)+ c= a+ (b + c) (ab)c = a(bc) (Associative Law)
a+(b +c)= ab +ac (Distributive law)
Fractions:
To add two fractions numbers with the same denominator, we use the Distributive Law property:
a/b+c/b= 1/b*a+1/b*c =1/b(a+c) =a+c/b
To add two fraction with different denominators, we use a frequent denominator:
a/b+c/d = ad+bc/bd
Factoring
Here we can make use of Distributive Law to increase certain algebraic conditions. In rare case we need to repeal this method (again using the Distributive Law) by factoring an expression as a product of simpler ones. The easiest condition occurs when the given expression has a common factor as given below...
3x(x-2)=3x2 – 6
Elementary Algebra Concepts Problems
Q 1 : Find the larger number, -13 or -16?
Sol : If a number has a negative sign, we dont conclude the number by ony seeing the value, here we have to consider the negative sign. If the value of a number with negative sign increases, the actual value of the number is decreses.
-16,-15,,-14,-13,-12,-111,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0
so,-13 is larger than -16.
Q 2: List all the integers between -2 and 4.
Sol : -2,-1, 0, 1,2,3,4 these number are present in the -2 ,4
The -2, 4 between numbers are -1,0,1,2,3
Q 3: Reduce 14/35.?
Sol : 14/35
We divide 7 on both sides
2/5
Q 4: Simplify 8 -: 2//3?
Sol : We divide the given equation this is simple method the division inverse of multiplication
8
4*3 = 12
Q 5: Simplify 1/2 + 2/3?
Sol : 1/2+ 2/3
We take L.C. M on 2, 3
1*3/2*3 +2*2/3*2
=3/6+4/6 =3+4/6
=7/6
Q 6.12x=4?
Sol : x=4/12
x=1/3
Q 7: 3X+4y=5x-2y ?
Sol : 4Y+2y=5x-3x
6y=2x
y=2x/6
y=x/3
Q 8 : x-4=8?
Sol : We add +4 on both sides
x=8+4
x=12
Q 9: Factorize the given expression x2-9 ?\
Sol : The general form of
(a2-b2)=(a-b)(a+b)
So, x2-9= (x-3)(x+3)
Example: 4x+ 2 = 1
