30 + 1

20 - 1

You do the rest, and someone will check your work.

1. To find one more than 3 tens, you need to multiply the number 3 by 10 and then add 1.

3 x 10 = 30

30 + 1 = 31

So, one more than 3 tens is 31.

2. To find one less than four times five, you need to multiply the number 5 by 4 and then subtract 1.

5 x 4 = 20

20 - 1 = 19

So, one less than four times five is 19.

3. To find five added to six, simply add the numbers 5 and 6 together.

5 + 6 = 11

So, five added to six is 11.

4. The successor of a number is the number that comes after it when counting in order.

The successor of 28 is 28 + 1 = 29.

So, the successor of 28 is 29.

5. To find two more than two times tens, you need to multiply the number 10 by 2 and then add 2.

10 x 2 = 20

20 + 2 = 22

So, two more than two times tens is 22.

6. A composite number is a positive integer greater than 1 that has more than two positive divisors (excluding 1 and itself).

The greatest 1-digit composite number is 9.

So, the greatest 1-digit composite number is 9.

7. To find three added to three times three, you need to multiply the number 3 by 3 and then add 3.

3 x 3 = 9

9 + 3 = 12

So, three added to three times three is 12.
