Given: 4.659 x 104− 2.14 x 104
• Both have the same base and exponent → Can be subtracted easily
• For addition/subtraction: # of sig. figs = lowest # of decimal places
Compute 4.659×104 − 2.14×104. Round the answer appropriately. Express your answer as an integer using the proper number of significant figures (e.g. 12300).
