1.one more than 3 tens
2.one less than four times five
3.five added to six
4.successor of 28
5.two more than two times tens
6.the greatest 1 digit composite number
7.three added to three times three
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.
