- Hi how are you doing•(1 vote)
- At some point, is it necessary to memorize equations such as: 9 + 5 = 14 or

8 + 7 = 15?(1 vote)- Memorizing simple equations such as that is something that will come quite easily as you grow older. It is not necessary to remember them, but it would make your life so much easier and quicker. Plus it is something that over time, you will most likely remember them by heart whether you mean to or not.(2 votes)
