Number two
293
x 5

First step
Draw and arrow from 5 to 3. Now multiply 5 times 3. You'll get 15. Write the 5 on the bottom and regroup the 1 over the 9.
Second step
Draw and arrow from the 5 to the 9. Now multiply 5 times 9. You'll bet 45 BUT you also have to add the regrouped 1, to give you 46. Write the 6 on the bottom and regroup the 4 over the 2.
Third step
Draw and arrow from the 5 to the 2. Now multiply 5 times 2. You'll get 10 BUT you also have to add the regrouped 4, to give you 14. Write the 14 on the bottom. We're done, so there is no need to regroup.

Your product is...... 1,465

I'll walk you through solving number two. I see only one line, which means that it's either a line, line segment, or a ray.

After looking at the pictures, we can see that number two is a line segment. It ends in two dots (enpoints)

HELPFUL HINT
Area = multiplication (2 sides)
Perimeter = add (all sides)

For number two, they've given you a grey rectangle.
To find the length, count the number of boxes across the top.
You'll find that there are 5.
To find the width, count the number of boxes going down the side.
You'll find that there are 2.
Remember, to find the area, you multiply the length by the width.
This gives you the multiplication problem of 5 x 2
5 x 2 = 10
So the area is 10 square units

I'll walk you through solving number 2.
68 times 24
Make sure you draw arrows to help you remember what you are doing.

Step 1:
4 times 8
4x8 = 32
Write the 2 under the problem and regroup(carry) the 3.

Step 2:
4 times 6
4x6 = 24
Don't forget to add the regrouped number, 3
24 plus 3
24+3 = 27
Write 27 under the problem

This gives the first row an answer of 272

Step 3:
Skip down, under 272, write a zero

Step 4:
Multiply 2 times 8
2x8 = 16
Write the 6 under the 7, and regroup(carry) the 1 over the 6 (make sure that you crossed out the 3 from the previous regrouping.

Step 5:
Multiply 2 times 6
2x6 = 12
Don't forget to add the regrouped number (1)
12 plus 1
12+1 = 13
Write the 13 under the first row.

This gives our second row a total of 1,360

Step 6:
Add the first row and the second row
272 plus 1,360

272
+1360

TOTAL 1,632

Now I'll explain how to do number two.
First we need to multiply
3x3
The answer is 9, so write a 9 in the first box.
Now let's multiply the 3 times the other three (its in the tens place on top)
3 x 3 is 9, so write a 9 in the second box.

Now we need to hop over and multiply the 2, but before we multiply we need to hop down to the second row of boxes and write a zero in the first box.
ok
Now multiply the 2 times the 3 on top (in the ones place)
2x3 is 6
Write the 6 in the second box on the bottom.
Now multiply the 2 again times the 3 on top (this time the one in the tens place)
2x3 is 6
Write a 6 in the third box on the bottom.

Now that we are finished multiplying, we need to add the two numbers in the boxes.
99 plus 660

Our total answer is 759.

I will now walk you through solving number two.
42x30
Remember to ignore the zero, we can always put it at the end of the answer.
So this leaves us with
42
x 3

3 times 2 is 6

42
x 3
6

3 times 4 is 12

42
x 3
126

Now we add the zero to the end and ger
1,260 as our answer!

I'll walk you through number two.
5x3
That shouldn't take you very long, it's an easy one!
15
:)

5x30
If we see a zero like that, we can ignore it for now, and just add it to the back of the answer at the end.
If we ignore the zero, we are left with 5x3, which we just did and found out was 15.
When we put the zero on the end we have an answer of 150.

500x300
Lots of zeros here! Four to be exact. If we ignore all four of them, we have to remember to add four to the end of the answer.
We again are left with 5x3, which is still 15.
But when we add the four zeros onto the end we get an answer of 150,000.
