Break-the-Ten Meteor Rescue

Split one subtraction into two blasts and protect the planet.

RESCUE 1 OF 5

Solve 11 minus 2. How many should the first blast remove to reach ten?

1 / 5

11−2=?

11 − ? = 10then10 − ? = ?

FIRST BLAST: LAND ON 10

Choose the first blast that lands on ten.

Subtracting across ten can be split into two easier subtractions. First reach ten, then subtract the rest.

For 14 − 6, split 6 into 4 and 2. Calculate 14 − 4 = 10, then 10 − 2 = 8.

The two amounts you remove must add back to the original subtraction amount.
