We want to know: 90 × ? = 450
Divide 450 by 90:
450 ÷ 90 = 5
So, 90 should be multiplied by 5 times to get 450.
Step 1: Multiply 90 by 5:
90 × 5 = 450
Step 2: Subtract 5:
450 − 5 = 445
Step 3: Add 3:
445 + 3 = 448
So, the final answer is 448.
Step 1: 90 × 11 = 990
Step 2: 90 × 15 = 1350
Now substitute into the expression:
14 + 990 − 1350 = 14 − 360 = - 346
So, the final answer is - 346.
