Title: Learn to subtract 1-digit numbers from 2-digit numbers Pt. 2.

You already know how to subtract when you have to take a ten.
In this lesson, you'll learn how to use that to subtract with numbers that have both tens and ones.
Here's an example. 43 minus 7.
We start with the ones place.
We can't subtract 7 from 3, so we have to take a ten from 40 to make ten ones.
We cross out the 4 in 40 and we enter a 3 here to show we have 3 tens left.
Now we put a 1 here to show that we have 13 ones.
So now we have 13 minus 7.
13 minus 7 is 6, so we put a 6 in the ones place of the answer.
There's nothing to subtract in the tens place, so we bring down the 3 for the 3 tens we have left.
That gives us 36.
So 43 minus 7 is 36.
Another example. 65 minus 8.
We start with the ones place.
We can't subtract 8 from 5, so we have to take a ten from 60 to make ten ones.
We cross out the 6 in 60 and we enter a 5 here to show that we have 5 tens left.
And we enter a 1 here to show we have 15 ones.
Now we subtract 8 from 15.
15 minus 8 is 7.
There's nothing to subtract in the tens place, so we bring down the 5 for the 5 tens we have left.
That gives us 57.
So 65 minus 8 is 57.
Last example. 37 minus 8.
We can't subtract 8 from 7, so we have to take a ten from 30 to make 10 ones.
We cross out the 3 in 30 and we enter a 2 here to show that we have 2 tens left.
And we enter a 1 here to show we have 17 ones.
Now we subtract 8 from 17.
17 minus 8 is 9.
There's nothing to subtract in the tens place, so we bring down the 2 for the 2 tens we have left.
That gives us 29.
So 37 minus 8 is 29.
In the rest of this lesson, you'll work problems like these. You can use these boxes if you want, but you don’t have to.

Scientists Discovered Planets Even Better for Life Than Earth
Scientists Discovered Planets Even Better for Life Than Earth Teacherflix 3 צפיות • לִפנֵי 2 שנים

Out of all the planets in the Universe, Earth is clearly the best for life, right? Wrong. Earth may be great, but scientists have discovered a few worlds that could be even better for life. Behold, KOI 5715.01. Most of the contenders on our superhabitable planet list aren't the ones you could visit anytime soon. The top spot is held by one 3,000 light-years away from our Solar System. It exists in the Goldilocks zone of its star. So conditions wouldn’t be too hot or too cold for a key life-supporting ingredient to exist on its surface. Liquid water.

The 1960s in America: Crash Course US History #40
The 1960s in America: Crash Course US History #40 Teacherflix 3 צפיות • לִפנֵי 2 שנים

In which John Green teaches you about a time of relative tumult in the United States, the 1960s. America was changing rapidly in the 1960s, and rights movements were at the forefront of those changes. Civil Rights were dominant, but the 60s also saw growth in the Women's Movement, the LGBT Rights Movement, the Latino Rights Movement, and the American Indian Movement. Also, Americans began to pay a bit more attention to the environment. All this change happened against the backdrop of the Cold War and the Rise of Conservatism. It was just wild. John will teach you about sit-ins, Freedom Rides, The March on Washington, MLK, JFK, LBJ, and NOW. Man, that is a lot of initialisms. And one acronym.

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. Civil Rights stayed strong throughout the 1960s, beginning with the peaceful sit-in movement in 1960 in the South:
