What is #36- 4\div 2+ 6#?

Answer 1

#=40#

Always count the number of terms first. There are 3 terms. Keep them separate until each has been simplified to a single answer. In this case there is only one term which needs simplifying.

#color(blue)(36)color(red)(-4div2)color(purple)( +6)#

#=color(blue)(36)color(red)(-2)color(purple)( +6)#

To avoid errors in which terms are being subtracted, it is safer to place the adds at the beginning and the subtracts at the end.

#=color(blue)(36)color(purple)( +6) color(red)(-2)#

#=40#

To solve the expression ( 36 - \frac{4}{2} + 6 ), follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, perform the division: ( \frac{4}{2} = 2 ).

Then, perform the subtraction: ( 36 - 2 = 34 ).

Finally, perform the addition: ( 34 + 6 = 40 ).

So, ( 36 - \frac{4}{2} + 6 = 40 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
