Question

Describe two different strategies you could use to add l6 + 35 + 24 + 14.

Answer 1

Answer:

(16+35)+(24+14)

(16+14)+(35+24)

Step-by-step explanation:

This equation equals 89, basically what you would do is just add two numbers together and then add the sum of those two numbers, it makes the equation way easier to solve since you are not adding 4 numbers at a time, just 2.

Answer 2

Answer: 16 + 35 + 24 + 14 = 89

Strategy #1 : You could break them up.

.... 10+30+20+10=70  

.... 6+5+4+4=19

....70+19=89

Or, you can separate them into groups!

16+35=51

24+14=38

51+38=89
