@atrupar Doubling down on how bad at basic math he and the entire administration isn't a good look. These morons don't understand middle school math and expect us to believe they know how to run a country?

@howie_hua @MikeFlynn55 Divide each by 2. My new problem is 44 x 4 x 2 x 2.

44 x 4 = 176 (40 x 4) + (4 x 4)
2 x 2 = 4

176 x 4 = 704

But I guess I ended up using an 8 when multiplying 70 x 4. Hope it still counts.

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua @pwharris I broke 15 into 10 and 5.

10 x 36 = 360 (Full circle)
5 x 36 = 180 (Half circle)

From watching the Olympics, I know a 1.5 rotation is called a 540, and 360 + 180 = 540

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua I started at 73.
Subtracted 3 to get 70.
Subtracted 30 to get 40.
Then subtracted 4 to get 36.

Breaking the 37 into more manageable numbers makes the subtraction easier for me.

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua @mminas8 I broke the 27 into 25 + 2. Seeing the 25 made me think of money.

8 X 25 = 8 quarters = $2.00
8 X 2 = 16 pennies = $0.16

$2.00 + $0.16 = $2.16

8 x 27 = 216

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua Flip the problem - What is 50% of 30?

Half of a number is easier for me. Half of 30 is 15.

I used the model on the right, but then double checked with the original one on the left.

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua 2 ways.

1st - I was born in 1974, so they are 2 years younger than me. I'm 51, they are or will be 49.

2nd - On a number line. 2025 - 50 is 1975. I subtracted 1 too many. Add the -1 back and I also get 49.

(number line not to scale)

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua I added all the tens first to get 40. I was left with 3+5+7+9.

3+7= 10 (add that to my 10's group to now have 50)
5+9= 14 (another ten to get 60)

60 + 4 = 64

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua Traveling 6 miles in 5 min. means you will go 36 miles in 30 min.

Traveling 7 miles in 6 min. means you will go 35 miles in 30 min.

6 miles in 5 minutes is just a bit faster.

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua First thought - it is just less than 20 if I didn't need to be exact.

Second thought - reverse the numbers - 40% of 45.
10% of 45 is 4.5. I need four of those.

4.5 + 4.5 + 4.5 + 4.5 = 18.
(Solved this as 9 + 9 or (4x4) + 2)

@howie_hua Using your numbers, and estimating my height in cm. (I'm between 6' 4" and 6' 5" - but where exactly, I'm not sure and don't really care.)

I'm about 196 cm. So I would have about $280. All the little difference in exact height might add or remove a dollar, but I'll take it!

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua But playing around with the linking cubes, I found another interesting way.

[Ryan Dougherty @RyanM_Dougherty]

@howie_hua First way I saw it was --

6+9 = 15
7+8 = 15

15+15 = 30
