What's 22 times 5?
one hundred and ten
7.8 times 6.1 + 7.8 + 3.9, thank you,
7.8 × 6.1 ＋ 7.8 ＋ 3.9 = 7.8 × (6.1 ＋ 1) + 3.9 = 7.8 × 7.1 ＋ 3.9 = 3.9 × 2 × 7.1 ＋ 3.9 = 3.9 × (14.2 ＋ 1) = 3.9 × 15.2 = 59.28. It may be a printing error. The multiplication sign of the last operation symbol is wrongly printed as a plus sign
What is 1 plus [minus 2] plus [minus 3] plus 4 plus 5 plus [minus 6] plus [minus 7] plus 8 plus 9 plus [minus 10] plus [minus 11] plus 12?
1+4+5+8+9+12-2-3-6-7-10-11=39-39=0
