It's Mental Math Monday with guest @gfletchy! Graham wants to know how you would mentally calculate 6 × 5/8.

Hmmmm…
Difference of two squares comes to mind.
34x46=2x2x17x23
= (20-3)(20+3)x2x2
= (400-9)x4
=1600-36
= 1564
Or
Doubling and halving
34x46 = 17x92
17x100 - 17x8
1700-8(10+7)
1700-(80+56)
1700-(100+36)
1564
This is a good one!

I am starting with the factors:
4 x 4 x 2 x 11
32 x 11
32 x 10 = 320
32 x 1 = 32
320 + 32 = 352
Adjust for percentage
16% of 22 is 3.52

13/25 is just over 1/2
1/2 of 7/3 is 7/6
I don’t think 13/25 is enough over 1/2 to take 1.16(repeat) up to 1.5
So, it’s closest to 1.

That Time I Couldn't Hear
For 2 months, I had dramatic hearing loss. I had never been so acutely aware of how I organize my life & work around my ability to hear.

In all fairness, medicine is life or death, in its acute form. There aren’t a lot counting or calculus emergencies.
In its chronic form, as described, medicine is indeed similar to teaching.
