A 423,900.00 because cuatrocientos 400 veintitrés 23 mil so you add them which is 423 novecientos 900 and all convined is 423900.00
To memorize the irregulars, remember last words, like -é, -emos, <span>-éis, -án. Connect normal irregulars with these words. Boom, you make a future tense irregular.
Estar+emos=estaremos
Vivir+é=viviré</span>
I’m confused? I would like to help though
