The puzzle presents a simple story about a girl named Emma.<\/p>\n
When someone asked Emma her age, she did not just say a plain number.<\/p>\n
Instead, she replied with a mathematical expression: 50 + 10 x 0 + 7 + 2.<\/p>\n
The main question asks: \u201cHow old is Emma?\u201d<\/p>\n
At first glance, this expression looks like something you can easily calculate from left to right.<\/p>\n
However, if you calculate it straight from left to right, you might make a common mistake.<\/p>\n
To find Emma\u2019s true age, you need to follow the fundamental order of operations in mathematics.<\/p>\n
The order of operations is often remembered by acronyms like PEMDAS or BODMAS.<\/p>\n
This rule states that multiplication and division must always be performed before addition and subtraction.<\/p>\n
Let us break down Emma\u2019s answer step by step.<\/p>\n
The expression contains four numbers linked by addition and multiplication signs.<\/p>\n
First, identify the multiplication part in the expression, which is 10 x 0.<\/p>\n
According to the rules of arithmetic, any number multiplied by zero equals zero.<\/p>\n
So, 10 x 0 evaluates to 0.<\/p>\n
Now, replace 10 x 0 with 0 in the original expression.<\/p>\n
The expression now becomes 50 + 0 + 7 + 2.<\/p>\n
Since all remaining operations are additions, you can now add the numbers together from left to right.<\/p>\n
First, add 50 + 0, which equals 50.<\/p>\n
Next, add 7 to 50, which gives 57.<\/p>\n
Finally, add 2 to 57, which results in 59.<\/p>\n
Therefore, the final value of the expression is 59.<\/p>\n
Logically, Emma is 59 years old.<\/strong><\/p>\n This puzzle is a great reminder of why mathematical rules like the order of operations matter.<\/p>\n Without following the proper order, a simple equation can lead to completely wrong results.<\/p>\n Did you manage to get the correct answer on your first try?<\/p>\n","protected":false},"excerpt":{"rendered":"
