What is an example of an algebraic expression with at least 3 operations in it?
3 (x2 + 1)
What does sub mean in math?
In mathematics, "sub" is short for "subtraction." It is commonly used in mathematical operations to denote the action of subtracting one number from another. For example, in the expression "5 - 3," the "sub" indicates that 3 is being subtracted from 5.
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.
