a+b=c a plus b is c
c-a=b c minus b is a ; b taken from c leaves a
12÷3=4 twelve divided by 3 equals four
30=6×5 thirty is six times five 
6×5=30 six multiplied by five is thirty
7+3＜12 seven plus three is less than twelve
(a+b) bracket a plus b bracket closed
20:5=16:4 the ratio of twenty to five equals the ratio of sixteen to four
a:b∷c:d a is to b as c is to d
v=s/t v equals s divided by t; v is s over t
(a+b-c×d)+e=f a plus b minus c multiplied by d, all divided by e equals f
