Writing Algebraic Expressions Writing Algebraic Expressions Writing Algebraic expression for a word phrase for an expression. When solving real world problems will need to translate words into algebraic expressions. Write an algebraic expression is not a sentence. Writing algebraic expressions are made up of symbols. The expressions represent one or more quantity. Order of operations Order of operations with exponents Order of operations. Addition (a+b)
Subtraction (a-b)
Multiplication (ab)
Division (a/b)
Rules : Perform first calculations inside parentheses. All multiplications and divisions are working from left to right. Finally additions and subtractions are working from left to right. Know More About Definite Integral

Order of Operations with Exponents When the number is repeatedly multiplied by itself,and then we get the powers of that number. Here a• a is called the power of a, or "a squared." a• a• a is the third power of a, or "a cubed (a3)." The first power of a is a itself. Now, write aaaa is similar to place a small number 4: a4 ( "a to the 4Th"). That small 4 is called an exponent. It indicates the number of times to repeat a as a factor. 83 "8 to the third") means 8• 8• 8. Algebraic Expression Formulas A formula is an algebraic rule is evaluating some quantity. A formula is a statement. Learn More Calculate Critical Value Math.Tutorvista.com

They are like the personal Algebra solvers who would aid with Algbera problems anytime. Example :- A three digit number consists of 7, 8 and one more number. When these digits are reversed and subtracted from the original number the answer yielded will be consisting of the same digits arranged yet in a different order. Solve the word problem and find the another digit? Solution : Let the unknown digit = n.
The given number is then,
700 + 80 + n = 780 + n. When reversed the new number is, 100n + 80 + 7 = 87 + 100n. Subtracting these two numbers we get,
After solving, we get
693 = 99n. The digit can be arranged in 3 ways or 6 ways. We have already investigated 2 of these ways. We can now try one of the remaining 4 ways. One of these are n = 95 100n + 70 + 8 = 693 – 99n,
199n = 615
After solving, we get n = 3 Answer : The unknown digit is 3. Read More About Differentiation Definition
