It is: (-4)^2 +(-4) -9 = 3 when x is equal to -4
2/3
It is an algebraic expression, if there are numbers and variables. For example: 2x + 2 = 4x(7-5) 20-29 = -9/3x If there are ONLY numbers and NO variables, it is called an arithmetic expression. For example: 3+3+3+3 = 4+4+4 2+6 = 4+4
If you mean subtracting a negative number from another negative, then you simply add the second negative to the first number. For example: -3 - (-4)=1 -3 + 4 = 1 The double negative makes the equation an addition.
3/4 is equal to 0.75 in decimal form.
3+4
3+3+3+3
Addition, subtraction, multiplication or division? If addition, then 1/4 + 1/6 + 1/3 = 3/4
addition: 2+ 3= 5 -----------(?) (?) (sum) subtraction: 6- 2= 4 ---------------(?) (?) (difference) multipliation: 5x6= 30 ---------------(factors) (product)
2+4=6-2=4+3=7-4=3
Addition. Multiplication is a special case of addition where the operands are the same.ie 4*3 = 4 + 4 + 4 (or 3 + 3 + 3 + 3)
4
41
TechCrunch Edit: 10 - 7 - 5 - 4 + 3 + 6 = 3
3/4 is equal to 6/8
4+5=9
4^(-3) = 1/4^3 or 1/64
