How do I evaluate an expression?
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
How do you solve algebraic expressions step by step?
A linear algebraic equation is nice and simple, containing only constants and variables to the first degree (no exponents or fancy stuff). To solve it, simply use multiplication, division, addition, and subtraction when necessary to isolate the variable and solve for “x”. Here’s how you do it: 4x + 16 = 25 -3x =
How do you simplify numbers?
Some ways to simplify a number…Round it off. Create zeros. So 199 becomes 200.Round to an order of magnitude. Round a lot, to the nearest “power of ten”. … Slide the decimal point. Compact those zeros created by rounding. … Substitute a number you can remember. Instead of rounding, find a nearby number you can remember.
What does it mean to simplify an expression?
To reduce a fraction to its lowest terms by canceling to the lowest common factor for both numerator and denominator or to condense an algebraic expression by grouping and combining similar terms. Simplifying makes a algebric expression easily understandable and solvable.
Why do we simplify algebraic expressions?
By “simplifying” an algebraic expression, we mean writing it in the most compact or efficient manner, without changing the value of the expression. This mainly involves collecting like terms, which means that we add together anything that can be added together.
