Question
In a certain mathematical system, + means - , - means X, X means decimal point(.) and decimal point(.) means + . For example, 52.67 + 23 - 2 equals 73, what would be the value of 8123.612 - 4578 + 2175 ?
Solution
Sure, let's solve the problem step by step:
Given that in this mathematical system, + means - , - means X, X means decimal point(.) and decimal point(.) means + .
So, the given expression 8123.612 - 4578 + 2175 changes to 8123+612 X 4578 - 2175.
Now, let's solve this step by step:
- First, perform the addition: 8123 + 612 = 8735
- Then, perform the multiplication: 4578 X 2175 = 9952450
- Finally, subtract the two results: 8735 - 9952450 = -9943715
So, the value of 8123.612 - 4578 + 2175 in this mathematical system is -9943715.
