(36-25)÷2=5.5 25+5.5=30.5 36-5.5=30.5 I understood. 30,5 smaller than 35
√25=5 √36=6 That's why I understood √35 is between from 5 to 6. In that case Why do we need to 30,5?
I don't understand to relative the number of 30,5. What does it mean? And next, I want to know how to find the number 5,91
Would you tell me the way please?
