• i dont think that people use math that much anymore, they use calculators
• Hi, you still need to know math to be able to use calculators in a good way. So keep learning math and you will do well with calculators too :) Without knowledge in math a person cannot keep learning and doing things with math, even if they have a calculator.
• I think i know that question?
Hi dsupraja05
So like he said when you multiply you half to add to get your awenser beacuse when you stack your numbers you will just have a number cake so that is why you add. -I think
• Thank you for helping and teaching us!
• Why do I keep failing?!😭
• 6742 x 23 well when you finish mulipling the 3 you add a zero below the ones place because 20+3 = 23 the zero you add is cause the 2 is the tens place then you multiply 2 x 6742

• I don’t get it. When I do all the steps it says I did it wrong
• Then you have a math error somewhere. Without seeing your actual work, I can't tell you where the error is. Use the hints to compare your work with the work in the exercise. This would help you find your error and avoid future mistakes.
