8*2*5 should be (8+2)*5

I'm sorry for all the errors. I'll leave this thread alone before I get edited like another thread.

Or... you could double check your work before posting?

Neat trick: Change the = to == and paste the line in PARI. If you get a 1, you're good.

I've decided I'll divulge my methods (even though I'm not meant for this forum), which mostly rely on a multiplicative partition, of an easy to get to, relatively nearby or exact value:

48=8*6*1= 8*(2+5+8-9)*(9/(3*3))
49=7*7 = (8+2+5-8)*((9/9)+3+3)
50=10*5+0= ((8+2)*5)+(8-9+(9/(3/3)))

Why no! These posts are perfect as they are. As is this post - https://mersenneforum.org/showthread...151#post505151

Ooops, you got edited again. Bummer!

Btw, by Godwin's law - a thread is over once Hitler or profanity is invoked.

Maybe people (except those who promised to leave the thread and lied) could continue - preferably without expletives?

Just a quick note: 50 above is wrong, so start from 50, not from 51.

50=(8+2)*5+8-9+9/3/3
51=(8+2)*5-8+9*9/3/3
52=(8+2)*5-8+9+9/3/3

[bsquared]

53 = 8 * 2 * 5 - 8 - 9 - 9 - 3/3
54 = 8 * 2 * 5 - 8 - 9 - 9 - (3 - 3)
55 = 8 * 2 * 5 - 8 - 9 - 9 + 3/3

But this is fun activity, and posting 2-3 more lines from time to time is ENOUGH!
You (general you) don't need to post 100 lines, to show us that you know to add and subtract or know how to use Excel. When you have few minutes relax from your daily job, or get your coffee break, post one more line. Don't do this 20 times per day, either. This is meant to be fun, and do not take it as a task where you need to spend hours and computing powers to post 30 lines. It make our life miserable (to check them all), and that especially if half of them are wrong. At this stage it is still easy, so you don't need to boast or waste computing power. Keep it fun. (Edit: and check your work!)

Just my two cents.
