Which operation to be done first Addition or Subtraction in order of operation? In this lecture, you will learn how to apply BODMAS or PEMDAS rule correctly. There may be situation arises where numerical expression contains addition and subtraction sign both. Here confusion may arise, which operation should be done first? To avoid such situation you must know correct definition of BODMAS or PEMDAS rule. A numerical expression is an expression that contains only numbers and operators. To evaluate, or find the value of a numerical expression, use a set of rules called the order of operations. Order of operations of BODMAS or PEMDAS rules are given as follows. (a) Perform operations in Parenthesis. (b) Evaluate numbers with Exponents. (c) Multiply or Divide from left to right. (d) Add and Subtract from left to right. As per BODMAS or PEMDAS rule, addition and subtraction have got same priority. We add or subtract which ever comes first. Suppose you have first addition then subtraction then you start adding first then subtract. If you have subtraction first and then addition then you should start subtracting first then add. As for example, In numerical expression 2+3-5, first find sum of 2 and 3, which is 5 then subtract 5 from 6. You will find answer of the following questions in this lecture. Does addition or subtraction come first in order of operations? What comes first in order of operations addition or subtraction? In order of operations do you do addition or subtraction first? Is addition or subtraction first in order of operations? Which comes first in the order of operations addition or subtraction? The definition of BODMAS rule and PEMDAS rule have been explained in Hindi. You can learn how to use bodmas rule and pemdas rule while solving numerical expressions.
