i feel so dumb sometimes i cant add and subtract in my head >.<

It's okay, all you need is practice. Practice, pracTICE, PRACTICE

What are minuend and subtrahend?

Minuend is the number you "start with" in a subtraction. Subtrahend is the number take from the minuend. So in "3 - 2 = 1", 3 is the minuend and 2 is the subtrahend.

10.1-3.93 is so easy but a little bit hard

Note that 3.93 is only 0.07 less than 4. So we can subtract 4 from 10.1 to get 6.1 (or 6.10), then add back 0.07 to get a final answer of *6.17*. Have a blessed, wonderful day!

but what happens if you get an equation like this: 22-10.7?

ok, so the first thing i would do is line it up. 22.0 I would add the zero on top of the seven -10.7 21-10=11 and ten -7 is 3 So your answer is 11.3 Hope that helps

  Minuend is the number you "start with" in a subtraction.
  Subtrahend is the number take from the minuend.
  So in "3 - 2 = 1", 3 is the minuend and 2 is the subtrahend.

Video transcript

Let's try to calculate 10.1 minus 3.93. And I encourage you to pause this video and try it on your own first, and then we can think about whether we did it the same way. So let's just rewrite it, aligning the decimal and the different place values. So 10.1 minus-- the 3 is in the ones place, so I'll put it right under the 0-- 3.93. Now, let's just try to calculate this. Now, before we subtract, we want all the numbers on top to be larger than the numbers on the bottom. And we don't even have a number here. We could stick a 0 here. Let me do that in a different color here. We could stick a 0 here. 10.1 is the same thing as 10.10, but we still face an issue here. 0 is less than 3. 1 is less than 9. 0 is less than 3. So we're going to do a little bit of regrouping. So let's do that regrouping. So we could take a 10 away, one 10 away, and then one 10 is the same thing as 10 ones. So I could write a 10 in the ones place. And I could take one of those ones away so I'm going to have nine ones, and give that one to the tenths place. Well, one is 10 tenths. 10 tenths plus 1 tenth is going to be 11 tenths. Now, I could take one of those tenths away and give it to the hundredths place. 1 tenth is 10 hundredths. And now I have a higher digit in the numerator, or at least as equal in the numerator as I have in the denominator. So 10 minus 3 is 7. 10 minus 9 is 1. I have the decimal. 9 minus 3 is 6. And then I have nothing over here. So 10.1 minus 3.93, 6.17.
