Posted November 3, 2016 by Presh Talwalkar. Read about me, or email me.
Here we go again, another order of to work problem. This equation has actually been mutual on Twitter and Facebook and many civilization are confused about the correct answer.
7 + 7 ÷ 7 + 7 × 7 – 7 =
In the following video clip I define the answer and also present two different ways to simplify the expression.
What Is 7 + 7 ÷ 7 + 7 × 7 + 7 same To? The exactly Answer Explained
Or keep reading for a text explanation. . ."All will be fine if you use your psychic for her decisions, and also mind just your decisions." since 2007, i have dedicated my life to sharing the joy of game theory and also mathematics. Yellowcomic.com now has actually over 1,000 free articles v no ads thanks to ar support! assist out and get early access to write-ups with a pledge on Patreon.. . . . . . Psychic . Your . Decision . By . PRESH . TALWALKAR . . . . The exactly Answer
The correct answer is 50.
One method to watch this is to interpret the expression 7 + 7 ÷ 7 + 7 × 7 – 7 = into a situation about money.
The expression begins with 7, therefore you start out with $7.
The next component is “+ 7 ÷ 7.” This method you get a 1/7 re-publishing of $7. Due to the fact that a 1/7 share of $7 is $1, that means you obtain $1. At this point you have $7 + $1 = $8.
The next part is “+ 7 × 7.” This method you gain $7 more, repetitive 7 times. Because a $7 times 7 is $49, that means you get $49 in total. At this allude you have $8 + $49 = $57.
The last part is “- 7.” That method $7 is taken far from you. Friend subtract $7, therefore you finish up v $57 – $7 = $50.
The exactly answer is thus 50.
The expression can likewise be simplified by the bespeak of operations, often remembered by the abbreviation PEMDAS/BODMAS.
First advice Parentheses/Brackets, climate evaluate Exponents/Orders, then evaluate Multiplication-Division, and also finally advice Addition-Subtraction.
The expression 7 + 7 ÷ 7 + 7 × 7 – 7 has no bracket or exponents, so us evaluate multiplication and division.
7 ÷ 7 = 1 7 × 7 = 49
7 + 7 ÷ 7 + 7 × 7 – 7 = 7 + 1 + 49 – 7
Now we deserve to evaluate the enhancement and the subtraction from left come right.
= 8 + 49 – 7 = 57 – 7 = 50
The correct answer is 50.
