Here\u2019s the challenge:<\/p>\n

\"\"<\/p>\n

There are 5 sisters in the room.<\/strong><\/p>\n

Ann is reading a book.<\/strong><\/p>\n

Margaret is cooking.<\/strong><\/p>\n

\n
\n
<\/div>\n<\/div>\n<\/div>\n

Kate is playing chess.<\/strong><\/p>\n

Marie is doing laundry.<\/strong><\/p>\n

So, what is the fifth sister doing?<\/strong><\/p>\n

Take a moment to think before scrolling down.<\/p>\n

Many people assume she must be doing some different activity. But look closely.<\/p>\n

Chess is not a one-person game.<\/p>\n

\u2026<\/p>\n

..<\/p>\n

\n
<\/div>\n<\/div>\n<\/div>\n

.<\/p>\n

The answer: The fifth sister is playing chess with Kate.<\/p>\n

If Kate is playing chess, she must have an opponent. Since there are only five sisters in the room, the remaining sister is the one playing with her.<\/p>\n

Did you catch the trick?<\/p>\n

==============================<\/p>\n

Solve this math riddle from middle school<\/strong><\/p>\n

Recently, a new type of challenge has appeared on the net, although the quizzes themselves are not particularly new.<\/p>\n

It\u2019s about good old-school mathematics.<\/p>\n

Trying this kind of challenge is exciting and fun, especially if it has been a bunch of years since you last went to school.<\/p>\n

<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

It\u2019s important to think about it and try to remember those old rules of math your teacher kept writing on the chalkboard many years ago.<\/p>\n

In addition, you must exercise your competitive instinct as well, which is always fun.<\/p>\n

Can you figure out the solution for this math riddle \u2013 without a calculator?<\/p>\n

Okay, now onto the challenge itself.<\/p>\n

In the picture below, we see a mathematics problem made for middle schoolers.<\/p>\n

\"\"<\/p>\n

The challenge: are you able to solve it without a calculator?<\/p>\n

Remember the order of operations. What part should you solve first?<\/p>\n

Think about it carefully so you answer correctly!<\/p>\n

Below the next picture, you will find the correct answer.<\/p>\n

A<\/p>\n

B<\/p>\n

C<\/p>\n

Here\u2019s the answer.<\/p>\n

In evaluating the expression 6-1\u00d70+3\u00f73, we use the PEMDAS mnemonic device, which tells us the correct operator precedence.<\/p>\n

So applying theory to your question, we must evaluate the multiplication and division operations first, then the addition and subtraction. Therefore:<\/p>\n

6-1\u00d70+3\u00f73<\/p>\n

= 6-(1\u00d70)+(3\u00f73) [items within parenthesis are evaluated first]<\/p>\n

= 6-0+1<\/p>\n

= 7<\/p>\n

The answer is then 7.<\/p>\n

Did you get it right? Congratulations!<\/p>\n
