How are numerical expressions and algebraic expressions similar?
They both use PEMDAS or Order of Operation
What patterns are involved in multiplying algebraic expression?
use parentheses and distribute
When do you use substitution in real life math problems?
you don't.
Use the substitution method to solve the system of equations Enter your answer as an ordered pair?
Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.y = 2x + 5 x = 1
How can you use models to compare expressions?
what the heck
Why is it important to use order of operations to evaluate algebraic expressions?
I think it is important because you need to know it when you get older.
Why do you use letters in algebraic expressions?
the reason you use letters in algebraic expressions is because you don't know the number so a letter replaces it.
How will you simplify algebraic expressions?
use a calculator
How are numerical expressions and algebraic expressions similar?

What are some jobs that use algebraic expressions?
A math teacher!
Problems in algebraic expressions?
x+x use inverse operations
What is the difference between algebraic and numerical expressions?
Algebraic expressions use letters as variables to represent numbers. Ex. 5c-(2+x) x=2 c=12 Numerical expressions use numbers only. Ex. 12+(2-7)
Write one numerical expression and one algebraic expression then explain the difference between a numerical and algebraic expression is?
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
Simplifying algebraic expressions?
2-9h+6-5n use h=3 and n=2
What is the Real life use of algebraic identities?
They can be used to simplify expressions so that the solutions can be found more easily.
How do you apply a algebraic expressions for daily life?
we use algebraic expressions:for teachingfor cost computingin groceriesfor project evaluationsfor engineeringin architecturein mathematicsin banksfor billingfor manufacturing
Why are multiplication division addition and subtraction used in evaluating expressions?
If they are present in the expression you need to use them to evaluate the expression, if they are not, you don't. You would not use any of them - at least not explicitly - to evaluate sqrt[ln(pi)], for example.
