800 + 90 + 4 - 1 = 893
14 more than a nomber x
no, the absolute value does not change the subtraction into addition. it does however, change the difference to positive ( if the difference is negative)
addition
In the absence of parentheses, multiplication and division are carried out before addition and subtraction. In this case, add 5 to whatever is happening with the five and the two.
8*5 - 15
A variable is simply an unknown value. It can be represented by anything else other than numbers (since they won't be variables). For example, a+1 is a variable in an addition expression, b-c is a subtraction expression with two variables. Expressions need not be made up of only 2 items as well. The next line is a single expression as well: q-w-e-r-t-y-u-i+o+p-a+s+d+f+g-32h+124j+73k-l+z+2x+c+7v-b+4n-8m
Y/3 - 1/9 = 2/9

No, addition and subtraction are performed in any order. Consider 6 + 3 - 2. You can do it two ways:6 + 3 -1 = 9- 1 = 8, or 6 + 3 -1 = 6 + 2 = 8.

use PEMDAS this is called the order of operations and is an acronym. here is what is stands for P=Parenthesis E=Exponents M=Multiplication D=Division A=Addition S=Subtraction You have to do whatever is in the parenthesis first then go onto the exponents... then go to the next operation until all things are simplified. Then you can isolate you variable and find the value of it in the expression.
mathematical order of operations stands for: Parentheses Exponents Radicals Absolute Value Multiplication Division Addition Subtraction
Change is usually the value of an expression before some operation subtracted from the value after the operation. Occasionally, subtraction may be replaced by division.
