For example:-say 4 apples more 2, equal 6; 4 more 6 equal 10; 4 more 2 more 6, more 5, more 3, equal 20: or in a mathematical mode of expression, 4+2+ 6+5+3=20. For the word more, we use this mark+, and for the word equal, we make use of two parallel lines, thus =. That is to say:-4 more 2, more 6, more 5, more 3, equal 20. See card No. 26 for a full explanation. QUESTIONS. What is the use of Addition ? By what sign shall we know Addition? What is the sign of equality, or of the word equal ? Mark them on your slate.
