How do you do algebra step by step?
What are the basic rules of algebra?
The Basic Laws of Algebra are the associative, commutative and distributive laws. They help explain the relationship between number operations and lend towards simplifying equations or solving them. The arrangement of addends does not affect the sum. The arrangement of factors does not affect the product.
What are the 3 rules of algebra?
There are many laws which govern the order in which you perform operations in arithmetic and in algebra. The three most widely discussed are the Commutative, Associative, and Distributive Laws. Over the years, people have found that when we add or multiply, the order of the numbers will not affect the outcome.
What is the golden rule of algebra?
Do unto one side of the equation, what you do to the other! If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.
What is the golden rule in manipulating equations?
The golden rule when solving an equation is to always repeat what you do to one side of the = sign on the other side. The idea is frequently referred to as “change the side, change the sign” or similar, however these are just simplifications of the rule.
What is the first rule of algebra?
The First Rule of Algebra – Or, “No, Virginia – There Is No Subtraction!”

Expanding brackets
- To expand a bracket means to multiply each term in the bracket by the expression outside the bracket. For example, in the expression 3 ( m + 7 ) , multiply both. and 7 by 3, so:

How do you expand numbers?
To expand a particular number (from its standard form), we need to expand it into the sum of each digit multiplied by its matching place value (ones, tens, hundreds, and so on).
