how does 1^2 - 4 × 5 × (-3) equal 61 I dont get it need help for gcse revision
+23246 Order of Operations Rules say: do exponents before you do multiplication, divisions, additions, and subtractions, so:
1² - 4 x 5 x (-3)
= 1 - 4 x 5 x (-3)
Now the rules tell you do all multiplications and divisions -- in order, from left to right -- before you do any additions or subtraction:
= 1 - 20 x (-3) (a negative times a negative is positive)
= 1 + 60
Now you can do additions and subtractions:
= 61
