Text-based problems

Think about whether the gifted money stayed with the same two children. Did their total amount change, or only how much each child has?

First check what is being asked: how many more cars there are, not how many cars there are in total now.

1. Separate the two facts: how many cars were there at first and how many arrived later.
2. If no cars left, the increase equals the number of newly arrived cars.
3. You would add the starting number and the arrivals only if you were asked for the total number of cars now.

“How many more” asks for the change; “how many in total” asks for the final amount.

Think about how many runners remain ahead. There are three runners in total: this runner and the two competitors.

If this runner has overtaken both competitors, neither is still ahead. The place depends on how many runners are in front.

To find the total number of apples, add the amounts collected by both children.

Read the numbers in the text. The apple picture is only an illustration and does not show the exact amount.

Compare the old and new prices. Subtract the smaller price from the larger one to find the change in cents.

Buying the book leaves less money. Subtract the price of the book from the amount of money available.

Check: the money left plus the book price must equal the starting amount. Use the numbers in the text.

Books were taken twice, so subtract both amounts.

1. Subtract the books taken on the first day from the starting number.
2. Subtract the books taken on the second day from what remains.

You can also add the two amounts taken, then subtract that total from the starting number. Use the numbers in the text.

One euro is 100 cents. Add the values of the coins, then subtract the total from 100.

Apples are fruit, so they are not included in the number of vegetables.

1. The vegetables in this problem are the carrots and potatoes.
2. Add their quantities: 12 + 18.
3. The sum is the total number of vegetables harvested.
