If MAYA is M years, and you want to see how old she is in four. You would do M + 4. For example lets say you knew MAYA was 8. How old is she in 4 years? M + 4. Replace it ( 8 + 4 ), she would be 12 in 4 years. M could be any number age and it would be true. Her age + 4 = her age in 4 years. Hope this helped :)
