Mathemat:
Honestly, I haven't figured out how to solve it yet. Can the numbers themselves be any two-digit numbers?

But it can probably only be solved in the field of natural numbers.

I haven't figured it out yet either, although I was in eighth grade, so I must have done badly :)

 

The simplest: X=1, Y=100, Z=10000

I hope no comments are needed. :)

 

try saying X=0, Y=1, Z=2,

then:

a*0+b*1+c*2=SUM

 
joo:

try saying X=0, Y=1, Z=2,

then:

a*0+b*1+c*2=SUM


So what? Like, he'll fire me anyway?

MetaDriver, after all, has already answered.

 

Exactly, the task is simple. MD, kudos!

But what about 1 and 2 of the problems?

1: 1,2,4,8,16,32,64 - 7 in total. Who's smaller?

2: It's not clear yet, but definitely no more than 7.

the condition is like yes. but it can probably only be solved in the field of natural numbers.

I haven't mastered it yet either. although I sure did in eighth grade, I must have done poorly :)


DUDES!

You amaze me!!!

 
The task gets harder :) Medvedev can only call two-digit numbers :)

1) 7

MetaDriver already answered that, didn't he?

I didn't see the MD's answer
 

1) 1 2 4 8 16 32 64

2) 1 3 9 27 81
