Answer:
A mathematical sentence is the analogue of an English sentence; it is a correct arrangement of mathematical symbols that states a complete thought. ... For example, the sentence '1+2=3 1 + 2 = 3 ' is true. The sentence '1+2=4 1 + 2 = 4 ' is false.
15+35 (fifteen plus thirty five)
25x2 (twenty five into two)
5x10 (five into ten)
100-50 (hundred minus fifty)
100/2 (hundred divided by two)
45+5 (forty five plus five)
75-25 (seventy five minus twenty five)
80-30 (eighty minus thirty)
