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


Here we go again, one more order of to work problem. This equation has actually been common on Twitter and Facebook and many people are confused around the exactly answer.

7 + 7 ÷ 7 + 7 × 7 – 7 =

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

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

Or keep reading for a message explanation. . ."All will certainly be well if you usage your psychic for her decisions, and mind only your decisions." due to the fact that 2007, i have committed my life to share the joy of game theory and also mathematics. civicpride-kusatsu.net now has over 1,000 totally free articles with no ads many thanks to community support! aid out and get early accessibility to write-ups with a pledge on Patreon.

. . . . . . Mental . Your . Decision . By . PRESH . TALWALKAR . . . . The exactly Answer

The exactly answer is 50.

One way to view this is to analyze the expression 7 + 7 ÷ 7 + 7 × 7 – 7 = into a situation about money.

The expression begins with 7, for this reason you start out v $7.

The next component is “+ 7 ÷ 7.” This means you obtain a 1/7 re-superstructure of $7. Because a 1/7 re-publishing of $7 is $1, that means you gain $1. At this allude you have actually $7 + $1 = $8.

The next component is “+ 7 × 7.” This method you obtain $7 more, repetitive 7 times. Due to the fact that a $7 times 7 is $49, that way you gain $49 in total. At this allude you have $8 + $49 = $57.

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

The exactly answer is thus 50.

The expression can additionally be streamlined by the stimulate of operations, often remembered through the acronyms PEMDAS/BODMAS.

First advice Parentheses/Brackets, climate evaluate Exponents/Orders, climate evaluate Multiplication-Division, and finally advice Addition-Subtraction.

The expression 7 + 7 ÷ 7 + 7 × 7 – 7 has actually no parentheses or exponents, so us evaluate multiplication and division.

7 ÷ 7 = 1 7 × 7 = 49

This means

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

Now we have the right to evaluate the enhancement and the subtraction from left to right.

= 8 + 49 – 7 = 57 – 7 = 50

The exactly answer is 50.
