Mental Math

Mental Math means to do a math question in your head. Or meaning to show how you answered the question.

For example: 3659+2659=6318 mental math is showing how you got that answer. step by step.

9+9=18

50+50=100

600+600=1200

3000+2000=5000

5000+1200= 6200

6200+100= 6300

6300+18=6318

  2. Great job! I like how you showed it step by step. But maybe next time you should not put so much colors and also maybe add a picture. But overall great post!

  3. Nice post, Jasmine. I like how you showed us step by step. I noticed you used different colours for each place value. Like how the ones were purple and the tens were blue, to show what you're dealing with. Colours can be kind of distracting, but this is a really well done post.
