3 (x2 + 1)
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.
1+1=3
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
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.
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.
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)
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.

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.

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.
Difference in math is subtraction. For example, the difference between 10 and 7 is 3 (10 - 7 = 3).
