Tips
grammar
Verb + 不了 (-buliǎo) is the potential complement meaning 'cannot V'. So 算不了 = 'cannot count as'. Pair with 算得了 (suàndeliǎo, 'can count as') in the affirmative — though 算得了 is much rarer than the negative form.
usage
Almost always followed by 什么 ('anything') for the dismissive 'no big deal' sense: 算不了什么. The note 'does not count for anything / of no account' from CC-CEDICT captures the spirit — used to wave off compliments, complaints, or perceived slights.
