plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
7/10 - 2/5(4/10) = 3/10
-4 + -3 = -7
7 + 90 / 9 + 10 + 42 - 7 7 + 10 + 10 + 16 - 7 36
(7 x 4) - (2 x 9) = 10

Using BODMAS/BIDMAS/PEDMAS: 2 × 7 - 10 ÷ 9 - 4 = (2 × 7) - (10 ÷ 9) - 4 = 14 - 10/9 - 4 = 10 - 10/9 = 10(1-1/9) = 10(8/9) = 80/9 = 8.888.... ≈ 8.89

plus times plus = plus minus times plus = minus plus times minus = minus minus times minus = plus so when you subtract a number it is the same as adding its negative; for example 7 - 4 = 3 7 + (1)(-4) = 3
(-4 - 7) x 3 = -33
5 times 7 divided by 5 plus 3 minus 4 is 6.
4/5 minus 7/10 = 1/10
