13 - 4 + 15 ÷ 3 =13 - 4 + 5 = 9 + 5 = 14
13...... 9 plus 5 equals 14...... 14 minus 1 equals 13
2(1+2+3+4+5+6+7+8+9+10+11+12+13+14) is the same as the question of the next part is supposed to be 14 plus 14. the answer is simply 1+2 and so on until 14, and then multiply by 2. The answer is 210.
13
5/8 + 13/4 = 5/8 + 7/4 = 5/8 + 14/8 = 19/8 = 23/8
13 and 5/8 plus 7/8 = 13 and 12/8, or 14 and 1/2
2 + 5 + (3 x 2) + 4 +2 + 17 + (2 - 13) + 5 = 30
