DMAS – rule for simplifying numerical expressions are explained here with text and video.
D = Division
M = Multiplication
A = Addition
S = Subtraction
Let us take an Example 1:
764+200/10-4 x 32
= 764+200/10-4 x 32 >>WORK ON DIVISION
=764+20–4 x 32 >>WORK ON MULTIPLICATION
=764+20-128 >>WORK ON ADDITION
=784-128 WORK ON SUBTRACTION
=656 >>ANSWER
Let us take another Example 2:
= 58×460 / 46 + 647 -743
= 58x460 / 46 + 647 -743 >>WORK ON DIVISION
= 58×10 + 647 -743 >>WORK ON MULTIPLICATION
= 580 + 647 -743 >>WORK ON ADDITION
= 1227-743 >>WORK ON SUBTRACTION
=484 >>ANSWER
