“Dad, where had you been?” asked Jimmy.
“I had been to the attic, my son,” replied Dad. “And do you know what I saw there? There was a big web with 23 spiders and flies on it.”
“How many spiders were there?” asked the little boy with curiosity.
“Well, there were a total of 146 legs on the web,” answered Dad with a smile. “Now you can find out how many spiders were there by yourself. Can’t you?”
Can you help the little boy find out how many spiders were on the web in the attic?
