If “1812 Overture” is too easy, so you look for something else during the 30 seconds, and come up with “Pop Goes the Weasel” as a better answer, by all means use it. If you don’t have anything better, use your original answer!!! #pearlsbeforeswine

Of course you're not trying to go to 600 because we're already there. All that's left is to go 800, and there we are at 1400, having gone 808.
Re: The Official TPH Education Thread (POTENTIAL GAME DAY SPOILERS)
Again, just randomly smashing numbers together until we get to 1400. At what point is this going to make sense?

Is it random that 600 is the closest round number to 592? Is it random that 6 + 8 = 14?

No, it's why we're picking 600 specifically that seems random.seaborgium wrote: ↑Tue Nov 07, 2017 2:28 amAnd yet I consistently get to the correct answer.

Re: The Official TPH Education Thread (POTENTIAL GAME DAY SPOILERS)
Let's go back to the money analogy and move the decimal point. And so it will make more sense, let's tweak it to $10.00 tendered for a $5.92 purchase. What's the change?1400-592
Okay, you're adding 8 which gives you...
592
+ 8
You need 3 pennies to get to 5.95, then a nickel to 6.00. From there it's 4 $1 bills to $10. So 3 pennies plus a nickel plus 4 ones. That's $4.08. More correctly, you don't care how much it is, you just know the change is right. You added up to get to the amount tendered. The buyer gave up a $10 bill and got a burger and fries costing 5.92, plus they got 3 pennies, a nickel, and 4 dollars.
The idea is to do addition, which most people find easier than subtraction.
Starting from the smaller number, what do you have to add to get to the next 10? Then from that, what you do add to get to the next hundred? Then the next 1000, the next 10,000 and so on.
Let's try a couple more, from earlier in the thread:
1523 - 649
Adding 1 to 649 gets you to 650 (the next highest ten). Then it's another 50 to 700 (the next highest hundred). 50 +1 is 51.
From 700 to 1500 is 800. Now our running total is 851. But we've only counted up to 1500. We need another 23 to get to the desired total. Add 23 to 851 and we've got our answer: 874.
Spoiler
An alternate solution because the math is easy is to subtract 23 from both numbers. Why 23? That's the low digits in 1523. 649-23 is 626. Now solve 1500-626 as 74 (to 700) plus 800.
Of course, you could extend this one more digit and subtract 523 from 649. (No borrowing needed, so it's not too tough.) That gives 1000-126=874. 74 to get to 200 and another 800 to 1000.
Of course, you could extend this one more digit and subtract 523 from 649. (No borrowing needed, so it's not too tough.) That gives 1000-126=874. 74 to get to 200 and another 800 to 1000.
121-83
7 gets us to 90, 10 more to 100 (so 17), then another 21. 17+21 is 38.
Alternatively, carry a pocket calculator.

It's not random. You're going up to the next higher "useful" number.TenPoundHammer wrote: ↑Tue Nov 07, 2017 11:56 am But how do I know to the numbers? How do I know to go to 5.95 and then 6? It's so random
With pure math, you'd go to the next multiple of 10. Then from there, you go up to the next multiple of 100, then the next 1000 and so on. You do that so you only have to deal with one digit at a time. And you never have to worry about "carrying the 1" or "borrowing 1".
With money, it's a little more complicated. (Although some people "get" money easier because they deal with it often.) First, you go up to the next increment of 5 cents. That's all the pennies you need. You use nickels, dimes or quarters from there to get to an even dollar. Then it's paper money.
Let's try something. Try to forget everything we've been talking about. (OK - I'm using "we" generously. I just started here - this is my second post. Whatever. )
What is 10 - 3?
Spoiler
7
Next, 30-3
40-3
50-3
Spoiler
17, 27, 37, 47
Now, let's turn it around and add.
What do I have to add to 3 to get to these numbers? Don't use pencil and paper here. Solve it in your head.
10
20
30
40
50

Also, breaking it down still confuses me because adding the hundreds, tens, and ones still involves carrying.
