\nBoth are not equal. So John is correct.
\nExplanation:
\nElsie says that to solve 17 \u2013 9, she can take one from 17 and give it to 9 to make 10. So, 17 \u2013 9 is equal to 16 \u2013 10. John thinks Elsie made a mistake. A number bond is a simple addition of two numbers that add up to give the sum. In the above image we can observe a number sentence 17 \u2013 9 = 8. Break seventeen into two parts as ten and seven. Subtract nine from ten then we got one. ADD one with seven then we got eight. In the above image we can observe a another number sentence 16 – 10 = 6. Break sixteen into two parts as ten and six. Subtract ten from ten then we got zero. ADD zero with six then we got six. Both expressions are not equal. So John is correct.<\/p>\n
