SITUAÇÕES PROBLEMAS ENVOLVENDO ADIÇÕES ALGÉBRICAS (Parte 5)

Hi everyone, how are you? In this lesson, I'll show you how to solve four word problems involving algebraic addition. 1) In a city, the thermometer read 8°C in the morning. During the afternoon, the temperature rose 6°C and, at nightfall, the temperature dropped 4°C, remaining the same until midnight. What was the temperature at midnight? 2) Caio has R$ 30.00 in his bank account. He made the following transactions: Deposited R$ 40.00; Withdrew R$ 35.00; Deposited R$ 30.00; Withdrew R$ 50.00. After these transactions, what is the balance in Caio's account? 3) Archimedes was one of the most important mathematicians of Antiquity. He was born in 287 BC and lived 75 years. In what year did Archimedes die? 4) In a game, the winner is the one who scores the most points. Paulo won 18 points and lost 12. Ana won 25 points and lost 17. Who won the game? I hope these examples help you solve other similar problem situations.
