Question: According to starling.rinet.ru the first person singularis is: "кладý" for the verb: "клáсть" but the TA (Teaching Assistant) has stated that it is: "кладум". Is there some old form that is presently used in first person singular for this verb that you know of?

Starling result: 

Infinitive: клáсть

Present/future tense

Singular Plural

1 person кладý кладём

2 person кладёшь кладёте

3 person кладёт кладýт

What the TA has presented it to be: "клáсть: кладум, кладёшь; клал, клала"
(everything but the first person singular seems to match up). My guess is that the clown got it right because he has induced a lot of typos and mistakes. I guess he is their best student.

Answer: 
For some reason, Google translate pronounces an isolated *чем* or *с чем* (with е, not ё) [as *чём*](https://translate.google.com/#en/ru/with%20what). This is definitely incorrect. The phrase *["Лучше поздно, чем никогда"](https://translate.google.com/#ru/en/%D0%9B%D1%83%D1%87%D1%88%D0%B5%20%D0%BF%D0%BE%D0%B7%D0%B4%D0%BD%D0%BE%2C%20%D1%87%D0%B5%D0%BC%20%D0%BD%D0%B8%D0%BA%D0%BE%D0%B3%D0%B4%D0%B0)*, however, is pronounced correctly.
oh, there is a problem with a letter 'ё'
somebody trys to erase that letter from russian alphabet and history, and there was a rumor about try to make any law to change ё on е.
but anyway, this is a different sounds, and letters too.
чем and чём is two diffent words.
о чём ты говоришь? what do you talking about? a subject
чем ты это докажешь? how will you prove that? a property
