Kenya uses mental math to find the sum of 235 and 23. She uses 235, 20, and one other number. What is the missing number?

3

5

35

58

3

Step-by-step explanation:

235 + 23

She uses 235, so 23 is left

235 + something + something = 235 + 23

235 + 20 + something = 235 + 23

subtract 235 from both sides

20 + something = 23

20 + something = 20 + 3

the missing number is 3
