Posted November 3, 2016 by Presh Talwalkar. Read around me, or email me.
Here us go again, one more order of to work problem. This equation has been common on Twitter and Facebook and many people are confused about the exactly answer.
7 + 7 ÷ 7 + 7 × 7 – 7 =
In the following video clip I describe the answer and present two different ways to simplify the expression.
What Is 7 + 7 ÷ 7 + 7 × 7 + 7 equal To? The correct Answer Explained
Or keep reading for a text explanation. . ."All will certainly be well if you use your mind for your decisions, and mind just your decisions." due to the fact that 2007, ns have committed my life to sharing the happiness of game theory and mathematics.

Your . Decisions . By . PRESH . TALWALKAR . . . . The correct Answer
The exactly answer is 50.
One means to check out this is to translate the expression 7 + 7 ÷ 7 + 7 × 7 – 7 = into a situation around money.
The expression begins with 7, for this reason you start out with $7.
The next part is “+ 7 ÷ 7.” This means you obtain a 1/7 re-publishing of $7. Due to the fact that a 1/7 share of $7 is $1, that method you gain $1. At this allude you have actually $7 + $1 = $8.
The next part is “+ 7 × 7.” This method you get $7 more, repeated 7 times. Due to the fact that a $7 times 7 is $49, that means you acquire $49 in total. In ~ this point you have $8 + $49 = $57.
The last component is “- 7.” That means $7 is taken away from you. You subtract $7, for this reason you end up v $57 – $7 = $50.
The correct answer is therefore 50.
The expression can also be streamlined by the order of operations, regularly remembered through the acronyms PEMDAS/BODMAS.
First evaluate Parentheses/Brackets, then evaluate Exponents/Orders, then evaluate Multiplication-Division, and also finally advice Addition-Subtraction.
The expression 7 + 7 ÷ 7 + 7 × 7 – 7 has actually no bracket or exponents, so us evaluate multiplication and also division.
7 ÷ 7 = 1 7 × 7 = 49
7 + 7 ÷ 7 + 7 × 7 – 7 = 7 + 1 + 49 – 7
Now we have the right to evaluate the addition and the individually from left come right.
= 8 + 49 – 7 = 57 – 7 = 50
The exactly answer is 50.
