Posted November 3, 2016 by Presh Talwalkar. Read around me, or email me.

Here we go again, an additional order of work problem. This equation has actually been shared on Twitter and Facebook and also many civilization are confused about the exactly answer.

7 + 7 ÷ 7 + 7 × 7 – 7 =

In the following video I explain the answer and present two various ways to leveling the expression.

**What Is 7 + 7 ÷ 7 + 7 × 7 + 7 equal To? The correct Answer Explained**

Or keep reading for a message explanation.** . ."All will be fine if you use your mental for her decisions, and also mind just your decisions." because 2007, ns have dedicated my life to share the joy of video game theory and mathematics. aramuseum.org now has over 1,000 free articles v no ads many thanks to neighborhood support! aid out and get early access to write-ups with a pledge on Patreon.**

**. . . . . . Mental . Your . Decision . By . PRESH . TALWALKAR . . . . The correct Answer**

The correct answer is 50.

One method to view this is to translate the expression 7 + 7 ÷ 7 + 7 × 7 – 7 = right into a situation about money.

The expression begins with 7, so you start out through $7.

The next part is “+ 7 ÷ 7.” This means you obtain a 1/7 re-superstructure of $7. Since a 1/7 re-superstructure of $7 is $1, that method you obtain $1. At this suggest you have actually $7 + $1 = $8.

The next part is “+ 7 × 7.” This means you gain $7 more, repeated 7 times. Due to the fact that a $7 time 7 is $49, that means you obtain $49 in total. In ~ this allude you have $8 + $49 = $57.

The last part is “- 7.” That means $7 is taken far from you. You subtract $7, for this reason you end up v $57 – $7 = $50.

The exactly answer is therefore 50.

The expression can additionally be streamlined by the bespeak of operations, frequently remembered by the abbreviation PEMDAS/BODMAS.

First advice **P**arentheses/**B**rackets, then evaluate **E**xponents/**O**rders, climate evaluate **M**ultiplication-**D**ivision, and finally advice **A**ddition-**S**ubtraction.

The expression 7 + 7 ÷ 7 + 7 × 7 – 7 has no clip or exponents, so we evaluate multiplication and also division.

7 ÷ 7 = 1** 7 × 7 = 49**

**This means**

**7 + 7 ÷ 7 + 7 × 7 – 7 = 7 + 1 + 49 – 7**

**Now we can evaluate the addition and the individually from left come right.**

**= 8 + 49 – 7 = 57 – 7 = 50**

**The correct answer is 50.**
