I would say we use letters in mathematics so you can understand the problem more or whats really happening for example if they ask you question about how many people went to the party and bought stuff without the letters and only numbers you'll be confused...like umm...how many people went what are the stuff they bought.Or another example is if the question only had an empty graph.People would be like what do I have to do with the empty graph.What's the problem etc.So math problems without letters would be confusing.

3. increased long-term challenges - A person who does not invest timely and in the right things can end up not earning any money from these investments. Hence, he will not be prepared for further challenges that will come once he ages. He cannot have enough money by the time he retires.

33,000 in scientific notation​
const2013 [10]

Answer:

3.3 × 10^{4}

Step-by-step explanation:

1. Move the decimal in 33,000 to the left until the number now has a value between one and ten

<em>Original number:  </em>33,000.

<em>New number:  </em>3.3000 (3.3)

As you can see the decimal has been moved to the left four times.

2. Now we need to plug it into the "scientific notation formula" which looks like this:  x × 10^{y}. 'x' will be the number we just got (3.3) and 'y' will be the number of times we moved the decimal (4).

3.3 × 10^{4}

I hope I explained this good for you. Let me know if you need more help!
