Question

Complete the table and by inspection of the table, find the solution to the equation m + 10 = 16.   

m	1	2	3	4	5	6	7	8	9	10	______
m + 10	______	______	______	______	______	______	______	______	______	______	______

Answer 1

For m + 10, the table can be constructed as follows.

m	m + 10
1	1 + 10 = 11
2	2 + 10 = 12
3	3 + 10 = 13
4	4 + 10 = 14
5	5 + 10 = 15
6	6 + 10 = 16
7	7 + 10 = 17
8	8 + 10 = 18
9	9 + 10 = 19
10	10 + 10 = 20

By inspection, we can find that m = 6 is the solution of the above equation as for m = 6, m + 10 = 6 + 10 = 16
