To some degree, you have to start memorizing them. Mathematics, these kind of require the most practice and Problems are- when you're getting started off in To learn multiplication in a little bit, but these types of You a sense of how to do these types of problems. What is 8 plus 7? Well, if you can still read I'll just continue to confuse you because I'll write Nice, I want to do a few more problems using it. You gave me 5, I'm going to have 11 either way. If I have 5 avocadosĪnd you give me 6, I'm going to have 11.
Order- 5 plus 6 is the same thing as 6 plus 5. To try this on a bunch of problems and you'll see And I'm going to try it inĪ different color so we don't get all confused. Can you switch the two numbersĪnd get the same answer? Well, let's try that. Question, what is 6 plus 5? Well, we're now Actually, my phone is ringing,īut I'm going to ignore the phone because you're Than figures, so you can't necessarily do it Is a hard problem is because the answer has more numbers I'm going to do it inĭifferent colors now. I want to draw the number lineĪgain, actually, I have a line tool, so I should give youĪll those ugly looking lines that I've been giving you. You'll do these problems in like half a second. More practice you do- you'll hopefully memorize these and And just so you know, if you'reĪ little daunted by this initially, you can always
Number line you start at 8 and you add 1. Increased it by one, by two, by three, by four. Number line, or we go to the right on the number So all the numbers I'm using are kind of in it. So number line, I just writeĪll the numbers in order. How I do it in my head when I forget- if I don't You to another way of thinking about this. So how many totalĪvocados do I have now? That's 1, 2, 3, 4,ĥ, 6, 7 avocados. So you know that these are the ones you're giving me. Think it was a fruit, even if you ate one. And in case you don't know whatĪn avocado is, it's actually a very delicious fruit. What is 3 plus 4? This is, I think, a more Me give you something a little bit more difficult. Then you were to give me another avocado, how manyĪvocados do I now have? Well, let's see. In case you don't have this memorized or you haven'tĪlready mastered this. How to do this, but I'll kind of show you a way of doing this With, I guess we could say, some problems. Presentation or in a couple of weeks it will seem basic. Sal, addition doesn't seem so basic to me.
