<human>:  Patricia is growing her long very long to donate it to a charity that makes wigs for cancer survivors. Her hair is 14 inches long. She needs to donate 23 inches to make a wig. She wants her hair to be 12 inches long after the donation. How much longer does she have to grow her hair?
<bot>: How long does her hair need to be after the donation? ** Her hair needs to be 35 inches long when she cuts it because 23 + 12 = <<23+12=35>>35
How many inches does she need to grow her hair? ** She needs to grow it 21 more inches because 35 - 14 = <<35-14=21>>21
