Let’s solve each problem one at a time.

Problem 1:
Ellen had 380 legos, but she lost 57 of them. How many legos does she have now?
We start with 380 and take away 57.
Do the subtraction:
380 - 57
Break it down:
380 - 50 = 330
330 - 7 = 323
So Ellen has
323 legos left.

Problem 2:
Arthur baked 35 muffins. How many more muffins does Arthur have to bake to have 83 muffins?
He wants 83 total, and already has 35.
So we subtract what he has from what he wants:
83 - 35
Break it down:
83 - 30 = 53
53 - 5 = 48
Arthur needs to bake
48 more muffins.

Problem 3:
Willy has 1,400 crayons. Lucy has 290 crayons. Jacob has 7 crayons. How many more crayons do they have altogether?
First, add all their crayons together:
Start with Willy + Lucy:
1,400 + 290 = 1,690
Then add Jacob’s:
1,690 + 7 = 1,697
Altogether, they have
1,697 crayons.
(Note: The question says “how many more” — but since no comparison is given (like “more than someone else”), it likely means “how many in total.” So we’re adding them up.)

Final Answer:
1. 323
2. 48
3. 1,697
