To solve these you have to follow the orders of operation(BEDMAS), which means brackets, exponents, division, multiplication, addition, subtraction all in that order. A) This is false. 7x6+4=46 and does not equal 7x10 or 70. B) This is false as well. The answer haste be 19 and 16-(4+7) does not equal 19. You add up what is in the brackets first and then subtract. This means that C and D have to be true. C) 10+(6/3)=12 10+2=12 True D) 2+5x7=37 2+35=37 Also true
