  • Ugh! I have $3 right now, but my mom said everyday I don't do the dishwasher she is going to take away $3 from my bank account and I haven't washed the dishes in 3 days! Lucky for me I just got $10 but I still don't know how much money I have in total!
  • Oh that's easy! Just use this card trick!
  • The card trick? How are cards going to help me?
  • Use the cards to help you visualize the problem
  • Oh I think I get it now!
  • The black cards are positive integers and the red cards are negative integers!
  • What is BEDMAS?
  • To solve the problem you use BEDMAS
  • BEDMAS stands for Brackets Exponents Division MultiplicationAdditionSubtractionWhen ever you solve a problem you do the steps in this order. Oh and by the way, if you can do multiplication before you do division if it comes first, same with addition and subtraction
  • So if -3 x +3 =-9 because a - times a + are equal to a -, and+3 + -9 =-6 because the - was greater then the +, and-6 + +10 = +4 because the + was greater then the -, then I have $4!
  • Ok so if I started with $3, and my mom takes away $3 every time I don't do the dishwasher, which has been 3 times, and I just got $10 my problem should look like this!
  • GOOD JOB!
  • Thank you so much! Now I know how to solve problems with BEDMAS and exponents!
