When you subtract zero from any number, the result is the original number. This is because subtracting zero does not change the value of the number.

In this case:

310 - 0 = 310

This operation is based on the identity property of subtraction, which states that any number minus zero is the number itself. So, subtracting zero from 310 leaves you with 310.

When you add zero to any number, the result is the original number. This is because zero has no value and does not change the value of the number it is added to.

In this case:

520 + 0 = 520

The number 520 remains the same because adding zero does not change its value. This principle is known as the identity property of addition.

The series given is 105, 110, 115, 120, 125,...

This is an arithmetic sequence where each number increases by 5.

To find the next number, add 5 to the last number in the series:

125 + 5 = 130

So, the next number in the series is 130.

To find out how many stickers are now in the drawer, you need to add the number of stickers Pamela placed in the drawer to the number of stickers that were already there.

Here's the calculation:

118 (stickers in the drawer) + 172 (stickers placed by Pamela) = 290 (total stickers)

So, there are now 290 stickers in the drawer.

To find out how many pine trees the park will have after the workers plant more trees, you need to add the number of trees being planted to the current number of trees.

Here's the calculation:

168 (current pine trees) + 122 (pine trees to be planted) = 290 (total pine trees)

So, the park will have 290 pine trees.

Write down the numbers: 586

369

Subtract the units place:

6 - 9: Since 6 is less than 9, we need to borrow from the tens place.

Borrowing 1 from the tens place changes the 8 to 7 and makes the 6 into 16.

16 - 9 = 7.

Subtract the tens place:

7 - 6 = 1 (since we borrowed 1 from the tens place).

Subtract the hundreds place:

5 - 3 = 2.

Therefore, 586 - 369 equals 217.

To find out how many cabbages Tim and Dan grew in total, you need to add the number of cabbages each of them grew.

Here's the calculation:

187 (cabbages grown by Tim) + 135 (cabbages grown by Dan) = 322 (total cabbages)

So, Tim and Dan grew 322 cabbages in all.

To find out how many books Sally and Salma have together, you need to add the number of books each of them has.

Here's the calculation:

149 (Sally's books) + 218 (Salma's books) = 367 (total books)

So, Sally and Salma have 367 books together.

To find out how many plums Ronnie and Suzanne picked in total, you need to add the number of plums each of them picked.

Here's the calculation:

152 (plums picked by Ronnie) + 117 (plums picked by Suzanne) = 269 (total plums)

So, Ronnie and Suzanne picked 269 plums in all.

To find out how many sheep Dan and Mason raised in total, you need to add the number of sheep each of them raised.

Here's the calculation:

127 (sheep raised by Dan) + 141 (sheep raised by Mason) = 268 (total sheep)

So, Dan and Mason raised 268 sheep in all.

To find out how many seashells Melinda has now, you need to subtract the number of seashells she gave to Sarah from the total number of seashells she found.

Here's the calculation:

328 (total seashells) - 209 (seashells given to Sarah) = 119 (seashells remaining)

So, Melinda now has 119 seashells.

To find out how many baseball cards Jack has now, you need to subtract the number of baseball cards Benny bought from Jack's total number of baseball cards.

Here's the calculation:

734 (total baseball cards Jack had) - 341 (baseball cards bought by Benny) = 393 (baseball cards remaining)

So, Jack now has 393 baseball cards.

To find out how many purple marbles Dora has now, you need to subtract the number of marbles she gave to Josh from the total number of marbles she originally had.

Here's the calculation:

672 (total purple marbles) - 308 (purple marbles given to Josh) = 364 (purple marbles remaining)

So, Dora now has 364 purple marbles.

To find one hundred more than 546, you simply add 100 to 546:

546 + 100 = 646

So, one hundred more than 546 is 646.

To find out how many yellow balloons Linda has now, you need to subtract the number of balloons she gave to Cynthia from the total number of balloons she originally had.

Here's the calculation:

645 (total yellow balloons) - 168 (yellow balloons given to Cynthia) = 477 (yellow balloons remaining)

So, Linda now has 477 yellow balloons.

The pattern in the given sequence is that each number is decreasing by 6 from the previous number. Starting from 57, we subtract 6 to get 51, then subtract 6 again to get 45, and so on. Therefore, the missing number should be 33, which is obtained by subtracting 6 from 39.

To find the sum of 481 and 231, add the two numbers together:

481 + 231 = 712

So, 481 + 231 = 712.

Write down the numbers: 900

201

Subtract the units place:

0 - 1: Since 0 is less than 1, we need to borrow from the tens place.

Borrowing 1 from the tens place changes the tens place from 0 to 9 and makes the units place 10.

10 - 1 = 9.

Subtract the tens place:

9 - 0 = 9 (since we borrowed 1 from the hundreds place).

Subtract the hundreds place:

9 - 2 = 7 (since we borrowed 1 from the hundreds place).

Therefore, 900 - 201 equals 699.

To find out how many tens are in the sum of 570 and 430, first calculate the total sum:

570 + 430 = 1000

Now, convert the total sum into tens by dividing by 10:

1000 ÷ 10 = 100

So, 570 + 430 equals 100 tens.

To find the sum of seven hundreds and thirteen tens, we need to convert these quantities into their respective values in standard numerical form.

Seven hundreds is 7 × 100 = 700.

Thirteen tens is 13 × 10 = 130.

Now, add these two values together:

700 + 130 = 830

So, seven hundreds plus thirteen tens is 830.
