2 -8

3 -5 difference means subtract

4 minus four minus a negative three is -1

the problem changes to add +3 to -4 to get -1

5 product means multiply so -4 x 5 = -20

a plus times a minus gives minus

6 aminus times a minus gives a + so plus eighteen

7 quotient means divide so 49 / -7 = 7

like -7 x -7 += 49

8 quotient means division the / or _ is the sign of division

so the problem is read: (negative 21) divided by ( negative

seven over three)

dividing by -7/3 is the same as multiplying by 3/-7

that’s the part you have to remember

so -21 x -7/3

would you let me

multiply -21 x -1/3 and get 7 then multiply by 7 for 49

?

49 is correct

sum od a and b means a+b

difference of a and b means a-b

product of a and b means a*b

quotient of a and b means 1/b

The difference of two numbers means take the first number and subtract the second number.

The product of two numbers means multiply them together.

The quotient of two numbers means take the first number and divide it by the second number.
