As one way of agreeing - do you know how to say "you are right" in Hebrew? It's most peculiar, because there is no "right" - as in "right vs left". Hebrew has two separate "right" words! - "Right" as the direction is ימין, ימינה and a completely different word for "right" as in "you are right" – צוֹדֵק\ ת!

Examples:
הוּא חוֹשֵׁב שֶׁהוּא תָּמִיד צוֹדֵק.
He thinks he is always right.
אֲנִי לֹא יוֹדַעַת מִי צוֹדֵק פֹּה וּמִי טוֹעֶה*, אֲבָל חַיָּבִים לַעֲשׂוֹת שָׁלוֹם!
I don't know who is right here and who is wrong*, but we must make peace!
אֲנִי חוֹשֶׁבֶת שֶׁצָּרִיךְ לִכְתֹּב אֶת זֶה עַם "ע" וְלֹא עִם "א"!
רֶגַע.. אֲנִי אֶבְדֹּק… אַתְּ צוֹדֶקֶת!!! כָּל הַכָּבוֹד לָךְ!
I think you have to write it with an "ayin" and not with "alef"!
One sec… let me see.. you are right!!! Good for you!

As a mild variation of צוֹדֵק you could also say נָכוֹן – "correct." It's a very common way to express agreement, much more common than responding "correct" in English – here we use it in broader sense of just agreeing in general, and not only confirming the facts. 😊

Examples:
נִרְאֶה לִי שֶׁצָּרִיךְ לִפְנוֹת פֶּה...
נָכוֹן! אֵיךְ לֹא שַׂמְתִּי לֵב?! תּוֹדָה!
I think you have to turn here…
Right! How come I didn't notice? Thank you!

* Did you notice that we don't have "wrong" in the strict sense? We just use the negation in most cases, sometimes we may use "mistaken" (as I did in the example above), and most often again the word נָכוֹן will come to the rescue -
wrong answer – תְּשׁוּבָה לֹא נְכוֹנָה
It's just wrong – זֶה פָּשׁוּט לֹא נָכוֹן!
