Question

jo had some strawberries. he gave 45 to his teachers. then he dropped 15. Later he ate 13. finally he gave half of what he had to his buddy. now he has 10. how many did he have to start?

Answer 1

He had 83 to start..

83-45= 38

38-15=23

23-13=10

Or you can do inverse and add 10+13+15+45=83
