Ben has 12 pencils. Heidi has 10 fewer pencils than Ben. How many pencils does Heidi have? Choose the number sentence that you can use to solve the problem.
Explanation: Ben has 12 and Heidi has 10 less than Ben does then you subtract 12 - 10 = 2. So Heidi has 2 pencils, and I can’t choose the sentence because I can’t see the options.
