What is an example of an algebraic expression with at least 3 operations in it?
3 (x2 + 1)
What is a example of how numbers are used math?
1+1=3
Why is it important that you follow the steps of order of operations rather than solve the problem from left to right?
Solving via order of operations and solving left to right can give drastically different answers.For example, 3(3-2)2+8Left to right:3(3-2)2+89-22+872+849+857Order of operations:3(3-2)2+83(1)2+83*1+83+811
Why the order of operations necessary for simplifying numerical expressions?
Order of operations is essential so that a mathematical statement can be read the same way by every person who reads it. Take for example the expression: 9 * 2 / 18 + 2 * 3 Without order of operations, this expression can have many different interpretations. These are just 3, but there are many, many more! (9*2)/(18+2*3) = .75 ((9*2)/(18+2))*3 = 2.7 9 * (2 / 18 + (2 * 3)) = 55. So, we use order of operations so that 9 * 2 / 18 + 2 * 3 is equal to 7 every time. In other words, without order of operations, we couldn't write math down and communicate it from one person to the next. We couldn't even keep track of our own calculations from one day to the next. Without order of operations, mathematics as a science would just fall apart.
What is the difference in maths between squaring something and multiplying it?
In math, squaring a number means that the number being squared is multiplied by itself. For example, if you were to square the number 3, it would muliply on itself. 3 x 3. Multiplying is just a way to get 3 with a different number. For example, 3 x 4. You could multiply 3 and 3, but it's pretty much just going to be 3 squared. I realize I fumbled a bit in this. Math was never my strong suit.
Why do you have order of operations in math?
Because you will get different answers otherwise. For example, 2 + 5 * 3 If you did 2 + 5 first, you would get 7 * 3 = 21 but if you did 5*3 first, you would get 2 + 15 = 17 So which one: 21 or 17? The order of operations was agreed to avoid such confusion.
What two operations are associative in math?
In math, operators bound to the Associative Property are Addition and Multiplication.For example:1+2+3 = (1+2)+3 = 1+(2+3)1x2x3 = (1x2)x3 = 1x(2x3)
What do the parenthesis do in math?
Based on the order of operations (PEMDAS), it states all inside the parenthesis goes first. For example, if you had the problem (1+3) x 4, you would do the 1+3 first, then multiply it by 4.
What are the four fundamental math concepts used in evaluating an expression?
The fundamental math operations: 1. Multiplication 2. Division 3. Addition 4. Subtraction The operator performs the operations of the expression in the order from the left to the right.
What is an example of an algebraic expression with at least 3 operations in it?
3 (x2 + 1)

What does the differences do in math?
Difference in math is subtraction. For example, the difference between 10 and 7 is 3 (10 - 7 = 3).
What are the different ways in naming sets in math?
Roster Method, for example {1, 2, 3, 4,5, 6} Set builder, for example {x:x is an element of Natural numbers, x

What is fact family in first grade math?
Fact family in first grade math is using 3 numbers and using the operations: Addition and Subtraction.
