Question In each of the following, write the subtraction and addition sentences that follow from the given sentence.
(a) If 78 + 164 = 242, then,
If 78 + 164 = 242, then
242 – 78 = 164
242 – 164 = 78
(c) If 921 – 137 = 784, then,
Solution:
If 462 + 839 = 1301, then
1301 – 462 = 839
1301 – 839 = 462
(b) If 462 + 839 = 1301, then,
Solution:
If 921 – 137 = 784, then
784 + 137 = 921
921 – 784 = 137
(d) If 824 – 234 = 590, then,
Solution:
If 824- 234 = 590, then
824 – 590 = 234
