Balancing Equation Calculator

Introduction on learning how to balance equations:-

In this section let me help you on balancing equation calculator. Learn how to balance equations is the first step into learning chemical equations in chemistry. This is because each and every equation you come across while studying chemistry is and should be written in the balanced form. An unbalanced equation doesn't imply any meaning similarly as a sentence without a verb has no meaning. Thus, learn how to balance equations is an important step in chemistry.

This will also help us on numeral most commonly Chemical equations need to be balanced in order to uphold the most fundamental rule of science – the Law of conservation of matter. The total number of atoms of each element that takes part in a chemical reaction should be equal on the side of the reactants and products in the chemical equation.

Help on Linear Equation

Linear Equations

A set of linear equations having a regula solution set is called system of coincidents linear equations.Find values of three unknowns, given three linear equations in the three unknown variables. Linear equation in three unknowns x, y, z is report of parity of form ax + by + cz + d = 0 where a, b, c, d are real numbers with a ≠ 0, b ≠ 0 and c ≠ 0.

Solve two equations in x, y

* Two equations are given.

* Removing y variable.This can also help us on system of linear equation

* Substitute value of x in any one of two equations

* Solve them in the usual way.

* Thus the values of x and y are obtained.

Fraction Problems

In this section let me explain on fraction problems. Before i go more deeper on that let me explain what are the kinds of fraction.



I hope you might have come to an conclusion with the kind of fraction about what is all about fraction.


In this section let me also help you on how do you multiply fractions.


A fraction is a number that can represent part of a whole. The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on.

Examples on Probability

We have studied enough about what is probability and it's importance towards mathematics. Now i am going to help you probability examples with the solutions.

Questions on Probability.

Here is some Statistics and Probability Question Answers , which will explain how to find the mean , median and mode for the series of numbers

Question:1 The median of prime numbers between 51 and 80.

Answer: 53, 59, 61, 67, 71, 73, 79

Median = Middle-most score

Median = 67

Question:2 The mean of 31 results is 60. If the mean of the first 16 results is 58 and that of the last 16 results is 62, find the 16th result. This will also help us on types of lines

Answer: The sum of 31 results = 60 x 31 = 1860

The sum of first 16 results = 58 x 16 = 928

The sum of second 16 results = 62 x 16 = 992

:.16th result = (928 + 992) - 1860 = 60

16th result = 60

Solving Multi Step Equations

Introduction to solving Multi Step Equations.

If two expressions are in equal, then it is called as an equation. When we add, subtract, multiply or divide the similar number on both sides of the equation, the equation does not change. More than two steps are used to solve the equation is called as multi step equation. Now, we are going to see some of the problems on solving multi step equations.

Solving Multi Step Equations Problems:

Example Problems

Solve for the variable y: -20 = 3 (2 y + 8) + 4

Solution

-20 = 3 (2y + 8) + 4

Eliminate the parentheses,

-20 = 3 (2 y) + 3 (8) + 4

-20 = 6 y + 24 + 4

-20 = 6y + 28

Subtract 28 on both sides of the equation

-20 - 28 = 6 y + 28 – 28

-48 = 6 y

Divide by 6 on both sides of the equation

-8 = y

So, the answer is y = -8.I

Example on Decimal Number

Introduction

A decimal number consists of two parts: - a whole number and a decimal number. That is, we can write a decimal number as a combination of a whole number part and a decimal number part. For example; 2.34 can be written as 2 +. 34

The whole number part includes 2 and the decimal part includes 3 tenths and 4 hundredths.

Example on Decimal Number

Following are the few example on decimal number.

1. Write the decimal number 13. 4 in words

Solution

Step 1: Write the number on left of the decimal point as a whole number, 13= Thirteen

Step 2: We use the word “and” to denote the decimal number, the decimal point,”.” is written as “and”

Step 3: Write the number on the right side of the decimal point as a whole number, 4= four

Step 4: We write the place value of the last digit (the digit at the right end of the decimal part), the place value of the last digit 4 is tenths

Hence we can write, 13. 4 = Thirteen and four tenths

1. Write the number, 256. 007

Solution

Following the steps to write the decimal numbers in words, we get

256. 007 = Two hundred fifty six and seven thousandths.

Note on Multiplying Exponents in Math

In this lesson let me help you go through on multiplying exponents in math. I hope you will enjoy reading this and do practice this at home. so that you become quite familiear to all the sollution.
Introduction:
In math, exponents are used to indicate repeated multiplying the same number. Dealing with positive and negative exponents and simplifying expressions dealing with them is simply a matter of remembering what the definition of an exponent is.

• A positive exponent means repeated multiplying.
• A negative exponent means the opposite of repeated multiplying, which is repeated division

Multiplying Exponents
Exponents or Indices are used to tell how many times a factor must be multiplied by itself. The factor may be a number (constant) or a variable. Consider 9². The factor is 9 and is called as the base and the exponent or the index is 2. It means 9 must be multiplied 2 times 9 × 9.
We can also multiply the factors in exponential notation.Multiplication of variables or constants with exponents is simple and the process is the same for both numbers and variables. For example,
(2²)(2²) = 2 × 2 × 2 × 2
= 24
(x²)(x²) = x • x • x • x
= x4
If m is a positive integer and a є Real Number Set and a ≠ 0, then a × a × a × … m times is am and a × a × a ×…. n times is anand the product of am and an is
am × an = (a × a × a × … m times) (a × a × a ×…. n times)
